Hi all,
I would like to make a plot using surf. I have a time vector with 17281x1, frequency of 17281x1, and a signal of 161x1.
I would like to make a plot with surf(t,f,X). How should I reshape the array X to be able to use surf?

surf(X,Y,Z)
In the above X, Y, Z should be matrices of same size. In your case how this is possible?

f and t are the same size, however X is not. That is why I need to use the reshape function I believe, or any other fuction which would "resize" the array X to be able to use surf().
