semilogx error, vectors must be same length

Hi, I am trying to plot a graph with logarithmic scale with semilogx, however I have encountered problem using it.

I have checked that both Freq' and abs(Zexp01) are 31 by 24, so they are the same size. However I still encounter problem that says vectors must be the same size. May I know how to solve this?

Thank you!

Answer 1

[VBBV]

semilogx(freq,abs(Zexp01),'.')  % use freq 

[VBBV]

use

freq 

instead of

Freq 

and without transpose operator '

aye thanks! this works!

Answer 2

Plot them like this way then by removing the transpose operation:

plot(freq, abs(Zexp01), '.')
