Run function showing error on plot

I have already remamed the script to myPlot.m and removed it from path but it is still saying
workPlot
Error using plot
Vectors must be the same length.
Error in workPlot (line 10)
plot (freq, abs(fourierSpace));

How many elements do each of those variables have?
fourierSpace = fftshift(ifft(data));
this is the line above, if it helps I can provide the entire algorithm. It is my professors and I am required to run it
That doesn't answer my question. The error you are getting is telling you that the two variables don't have the same size. That means that one is larger than the other. The code you posted only shows the origin of one of the variables.
Can you figure out why these two variables might have different lengths? Could it have something to do with the Fourier transform being symmetrical, with one half often being discarded?
