Number of errors in openpivgui about openpiv-matlab

[alexlib]

imshow is a function from Image Processing Toolbox of Matlab. Make sure you have it installed or move to Python :) @markattard95

Hi :) sorry for my late reply but thanks for your prompt response.

I did install the IPT for Matlab but still some errors prevail. Please find the errors encountered here under.

_> Index exceeds matrix dimensions.

Truly appreciate your help.

I would like to add that these errors arise when I load the images into the software (the test images). I tried to convert them to .PNG format and load those but the same errors still persisted.

Hallo,
I'm having the same problem, here I can use any test files its working fine but when I upload my images for example 10 sequential images, only the first image was loading the rest not visible and shows error.
