Description

Basic Syntax and Line Specification

shortPeriodCategoryBPlot(nalpha,omega) plots vector omega versus vector nalpha. If nalpha or omega is a matrix, then the function plots the vector versus the rows or columns of the matrix, whichever are aligned. If nalpha is a scalar and omega is a vector, the function creates the disconnected line objects and plots them as discrete points vertically at nalpha. This function is based on the MATLAB^® plot function.

shortPeriodCategoryBPlot(nalpha,omega,LineSpec) plots short-period category A requirements specified by the line specification LineSpec.

shortPeriodCategoryBPlot(nalpha1,omega1,LineSpec1,...nalphan,omegan,LineSpecn) combines the plots specified by the nalpha, omega, and linespec. It sets the line style, marker type, and color for each line. You can mix nalpha, omega, LineSpec triplets with nalpha, omega arguments, for example, plot(nalpha1,omega1,nalpha2,omega2,LineSpec2,nalpha3,omega3).

Name-Value Arguments and Axes Specification

shortPeriodCategoryBPlot(___,Name,Value) plots an altitude envelope contour specified by one or more Name,Value arguments. Specify name-value arguments after all other input arguments.

shortPeriodCategoryBPlot(ax,___) draws an altitude contour plot onto the axes ax. Specify arguments as previously listed after the ax argument.

Return Line Objects

[line,bline] = shortPeriodCategoryBPlot(___) returns a vector of line objects lineobjects and a vector of boundaryline objects boundary_lineobjects. Use lineobjects and boundary_lineobjects to modify properties of a specific plot after it is created. Specify arguments as previously listed.

Examples

Plot MIL-F-8785C Short-Period Category B Requirements

Plot the reference MIL-F-8785C short-period category B requirements.

shortPeriodCategoryBPlot([])

Plot nalpha and omega Data Against Level 1 B Requirements

Plot nalpha and omega data against the level 1 short-period category B requirements using diamond markers.

nalpha = 1:10;
omega = rand(10)+1;
shortPeriodCategoryBPlot(nalpha,omega,"d","Level","1")

Plot MIL-F-8785C Short-Period Category B Requirements and Return Vectors of Line Objects and Boundary Line Objects

Plot the reference MIL-F-8785C short-period category B requirements. Return line objects and boundary line objects in h and b.

[h,b] = shortPeriodCategoryBPlot([])

h = 
  0x1 empty Line array.

b = 
  4x1 BoundaryLine array:

  BoundaryLine    (Level 1)
  BoundaryLine    (Level 1)
  BoundaryLine    (Level 2)
  BoundaryLine    (Level 2 & 3)

Input Arguments

nalpha — Load factor per angle of attack

scalar | vector | matrix

Load factor per angle of attack n/α, specified as a scalar, vector, or matrix, in g's/radian.

Data Types: double

omega — Short-period undamped natural frequency response

scalar | vector | matrix

Short-period undamped natural frequency response ω_nSP, specified as a scalar, vector, or matrix, in radians/second.

Data Types: double

ax — Valid axes

scalar handle

Valid axes, specified as a scalar handle. By default, this function plots to the current axes, obtainable with the gca function.

Data Types: double

LineSpec — Line style, marker, and color

string scalar | character vector

Line style, marker, and color, specified as a string scalar or character vector containing symbols. The symbols can appear in any order. You do not need to specify all three characteristics (line style, marker, and color). For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line.

Example: "--or" is a red dashed line with circle markers.

Line Style	Description	Resulting Line
"-"	Solid line
"--"	Dashed line
":"	Dotted line
"-."	Dash-dotted line

Marker	Description	Resulting Marker
"o"	Circle
"+"	Plus sign
"*"	Asterisk
"."	Point
"x"	Cross
"_"	Horizontal line
"|"	Vertical line
"square"	Square
"diamond"	Diamond
"^"	Upward-pointing triangle
"v"	Downward-pointing triangle
">"	Right-pointing triangle
"<"	Left-pointing triangle
"pentagram"	Pentagram
"hexagram"	Hexagram

Color Name	Short Name	RGB Triplet	Appearance
"red"	"r"	[1 0 0]
"green"	"g"	[0 1 0]
"blue"	"b"	[0 0 1]
"cyan"	"c"	[0 1 1]
"magenta"	"m"	[1 0 1]
"yellow"	"y"	[1 1 0]
"black"	"k"	[0 0 0]
"white"	"w"	[1 1 1]

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: "Level","1"

Note

These properties are only a subset. For a full list, see Line Properties.

level — Requirement level

"All" (default) | "1" | "2" | "3"

Requirement level to plot, specified as:

• "All"

• "1"

• "2"

• "3"

Data Types: double

Output Arguments

line — One or more line objects

scalar | vector

One or more line objects, returned as a scalar or a vector. These are unique identifiers, which you can use to query and modify properties of a specific line. For a list of properties, see Line Properties.

bline — One or more boundary line objects

scalar | vector

One or more boundary line objects, returned as a scalar or a vector. These are unique identifiers, which you can use to query and modify properties of a specific chart line. For a list of properties, see Line Properties.
