MATLAB: How to resolve this error..Index exceeds matrix dimensions. Error in Untitled (line 27) testIMG = imread([‘test\’ a(1).name]);

Best Answer

The only indexing occurs in a(1) . If this exceed the limits already, a is empty. So check, how a is defined, e.g. using the debugger, to find out, why it is empty.

You are passing Hist and testIDs to your cal_AP function. In that function your try to access Hist(tesIDs).

Hist has 4079 rows (set by picnum early in your code), testIDs does not have this limitation and rather grows as long as there are images in your file. If there are more than 4079 you will get that error.

Use the debugger to check the cause of the error: https://www.mathworks.com/help/matlab/matlab_prog/debugging-process-and-features.html . Set a breakpoint in the failing line, or even better let Matlab stop automatically at the error:

dbstop if error

Now run the code again until it stops. The error message is clear: one of the used variables does not have as many elements as requested:

size(ddd)
size(cvDuration_1)
size(cvTTP_1)
size(cvAMP_1)

The forum cannot suggest a way to fix the problem, because we cannot know, how these variables have been created. But the debugger will help you here also.
