How can you use svd() command on an uint8 matrix?

I am trying to use single value decomposition on the matrix for an image to do image compression. When trying to use the svd() command, it says my input must be single or double. For reference, the matrix is a 2583 x 4220 uint8 matrix. The image of which is a 3 x 3 matrix.

In order to run svd() on a uint8 matrix, you need to run your own svd() function that handles singular value decomposition on a uint8 matrix, and save the code in a file named '@uint8/svd.m' . In theory that should act to define svd on datatype uint8.

Most people find it easiest to

[U,S,V] = svd(double(YourMatrixNameGoesHere));
