i want find the determinant of the video matrix,,,, but video matrix size is X =76032 x 60.
Is there any function to convert such a video frames matrix into square matrix?
OR
how to reshape video frames into square matrix?
also to perform X*X' operation i want square matrix.
i am applying Gaussian process latent variable model to the texture video.
thanks...

You can run X*X' with non-square matrices also.
yes we can run X*X' with non-square matrices also.
But when i perform X*K*X' operation i got an error
inner matrix dimensions must agree

I don't think you really want a square matrix for your purposes. In particular as Jan pointed out X*X' is fine for non square matrices. You probably have an error in forming the matrix K so that it doesn't have the correct dimensions. It should be 60 x 60 in your case.

I doubt your image frame is 76,032 pixels high by 60 columns wide. When you get a frame, what does this show
[rows, columns, numberOfColorFrames] = size(yourImage)
That said, you can use imresize() to squeeze your image into any size you want, such as a square.

Actual video has 60 frames of size 288*352 and after applying imresize i have converted these RGB frames into 144*176 column vector which gives me 76032 x 60 size
My work is to analyse and synthesize video frames using Non-linear GPLVM
for that i have converted these frames into a column vector. is it a right way?
please help me, if there is another way to perform this method.

I have no idea. I've never heard of "Non-linear GPLVM"
