Cant figure out why my program isnt working

The file that is the input contains two columns of number data both 1x5

What error do you get, or what difference do you see between what you expect and what you get?

[Jan]

Without knowing any details of the problem, a meaningful answer is impossible.

[Cory]

Im getting:??? Undefined function or method 'hmwrk2' for input

arguments of type 'char'.

and

??? Index exceeds matrix dimensions.

[Cory]

I think if i can figure out why the index exceeds matrix dimensions il be good.

[Jan]

@Cory: Please be so kind and post a *complete copy* of the error message. We need 1. the line, which causes the error, 2. the error message itself, 3. size/type/contents of the used variables, if they matter.

The code you've posted does not contain the term "hmwrk2" and it is not clear which command causes the index overflow.

[Cory]

It says undefined function or method 'hmwrk2' after i enter the filename when im trying to run the script

However, It says index exceeds matrix dimesnions if i just copy paste the steps in to the program

the file contains column#1 1.2,1.6,1.2,1.6,1.2 (ft) column#2 9,12,3,12,9 (clock face)

Just giving this a glance. Matlab works in Radians. There are certain commands you can specifily use to get matlab to work in degrees but I do not see any of them here.

THhe problem:

You have been given a set of ASCII data files that contain directions for laying out

patterns in a field. The data files contain in the first column a distance to travel and in the second

column a direction heading. Unfortunately, the person who created the data did not have a good

understanding of orienteering and the direction headings are given as referenced to a clock face.

The pattern begins at the origin of a Cartesian coordinate system with the person facing 12

o’clock, see the figure below. The figure shows an example of the first step in the pattern being

a distance of 1.5 feet in the direction of 7 o’clock. All direction headings are given in terms of

this clock orientation.

The distance values

given are in feet.

There are 5 data files

provided on the L

drive for testing of the

program.

Write a script

file that will allow the

user to input from the

keyboard the filename

of the file that they

wish to analyze. Load

only that ONE data file

and plot the resulting

pattern. Once each

point forming the pattern has been located, find and designate on the plot which of the resulting

nodes was the farthest away from the origin. Also find and designate the center of the pattern as

defined to occur at the coordinate location corresponding to (average x, average y). When

plotting the resulting pattern on the Cartesian coordinate system, set the axes limits

appropriately.

Submit: A flowchart, a copy of the script file, and ONE example output screen that processes

ONE data file.

[Walter Roberson]

You are trying to run the script file by naming the input file on the command line. Don't do that. Just run the script file and let it prompt you for the input file.

[Cory]

Im new to this. I dont quite understand what your saying
