>> figure,imshow(A);
Error: File: imageDisplayValidateParams.m Line: 170 Column: 1
The function "findImageType" was closed with an 'end', but at least one other function
definition was not. To avoid confusion when using nested functions, it is illegal to use
both conventions in the same file.
Error in imageDisplayParseInputs (line 79)
common_args = imageDisplayValidateParams(common_args);
Error in imshow (line 220)
[common_args,specific_args] = ...

You have a file somewhere in which you have at least one function that is terminated with 'end' and at least one that is not. All functions defined in a file must use the same convention - this can either be to not use 'end' or it can be to use 'end', but you cannot mix and match. The most obvious example is if you use a GUIDE file, where all the auto-generated functions are not terminated by 'end' so any functions you add must also not be terminated by 'end'

There is a missing end in the function imageDisplayValidateParams. As far as I can see, this is a Matlab toolbox function called from imshow. This function should be valid, so if an end is missing, you must have edited it. This can happen by accident, if you start Matlab as admin and open toolbox files. Therefore it is strongly recommended not to work as admin.
Restore the file imageDisplayValidateParams.m from your backup. See e.g. Recent Versions in Windows.
