Subscripted assignment dimension mismatch

Hi everybody, can someone please help me with this error, below is my code

tic
X = imread('T1.jpg');

[CR,BPP]=wcompress('c',X,'image_c.wtc','aswdr', 'maxloop',11 ,'wname','bior6.8' );
CR

Xc = wcompress('u','image_c.wtc');

time=toc 

set(gcf,'Color',[1 1 1])

subplot(1,2,1); image(X);
axis square;
title('Original Image')
subplot(1,2,2); image(Xc);
axis square;
title('Uncompressed Image')
xlabel({['Compression Ratio: ' num2str(CR,'%1.2f %%')], ...
      ['BPP: ' num2str(BPP,'%3.2f')]})

Image T1.jpg is truecolor image, class is uint8.

When I start the program, display an error

??? Subscripted assignment dimension mismatch.

Thanks in advance!

Would you upload your 'T1.jpg' image??

[Wayne King]

With the error that you are reporting, I suspect your problem is that your input image does not have X and Y dimensions that are power of two in length.

size(X,1) and size(X,2) must be a power of two.

Thank you Wayne, my problem is solved thanks to you. Input image must have X and Y dimensions that are power of two in length.
