Matlab imagesc flip y axis.

I have visualized the matrix by transposing it and using the imagesc function to see the distribution of colors. All vectors have been resampled, processed and normalized between 0 & 1 individually. The imagesc plot gives me this result (fig 1): But, when I use the axis functionality to add x & y limits, I get this:

Matlab imagesc flip y axis. Things To Know About Matlab imagesc flip y axis.

As you can see the images in first row are now scaled equally on X and Y axis (Y axis is longer than the X-axis) even though the size of the image matrix is 100x100 for each image on first row. Can someone help with how to make images in first row look like squares than rectangles which I get currently. Thanks.F: the frequencies you want the spectrum evaluated at. fs: the sampling frequency of your signal. Then plot the spectrogram with: subplot(313); imagesc( T, F, log(S) ); %plot the log spectrum. set(gca,'YDir', 'normal'); % flip the Y Axis so lower frequencies are at the bottom. Note: The quality and interpretability of a spectrogram …Potentially easy matlab question here, but I've searched and can't sort out how to do this. I've got a variables, which plot like this: I simple want the x axis to be the y axis and vice versa.imagesc (x,y,C) displays C as an image and specifies the bounds of the x- and y-axis with vectors x and y.
