plotsigroi(msk,x) plots
signal x with color-coded regions based on the source and properties
in msk. If x is complex-valued, the function
plots its magnitude.
Consider a mask of binary sequences for two categories, ran and dom. Use the sequences to generate a signalMask object. Discard regions with fewer than 3 samples.
rng default
sq = randi(2,200,2)-1;
m = signalMask(sq,"MinLength",3,"Categories",["ran""dom"]);
Generate a sequence of 200 random numbers. Plot the regions of interest.
x = rand(200,1);
plotsigroi(m,x)
Plot the regions of interest using rectangular patches.
Example: signalMask(table([2 4;6 7],["male" "female"]')) specifies a
signal mask with a three-sample male region and a two-sample
female region.
Example: signalMask(categorical(["" "male" "male" "male" "" "female" "female"
""]',["male" "female"])) specifies a signal mask with a three-sample
male region and a two-sample female
region.
Example: signalMask([0 1 1 1 0 0 0 0;0 0 0 0 0 1 1 0]','Categories',["male"
"female"]) specifies a signal mask with a three-sample
male region and a two-sample female
region.
Input signal, specified as a vector.
Example: chirp(0:1/1e3:1,25,1,50) specifies a chirp sampled at 1
kHz.
Data Types: single | double Complex Number Support: Yes
Rectangular patch option, specified as a logical value.
plotsigroi uses rectangular patches to plot regions of interest
if patchflag is true.
