Hello,
The following code should give the following graph, but there is an error appearing which is "Undefined function 'plotSpec' for input arguments of type 'double'." So, any one knows what is the problem?
Thanks,
f=10;
time=2;
Ts=1/1000;
t=Ts:Ts:time;
x=sign(cos(2*pi*f*t));
plotSpec(x,Ts)

plotSpec is not a function in any MATLAB toolbox.
I find plotspec (lower case 'S') defined in a couple of user-contributed files that look like homework; the files vary too much to say that "plotspec" has a well-defined purpose.
