There is no variable xzycbcr defined in your code., I only see YCBCR

If I want to save can in the two variable in worlspace, then how I need to do?

True, thanks for pointing that out Daniel. I'll repeat below and delete the previous comment
save can YCBCR RGB
But please read Daniel's answer as he has a very good point regarding your variable name.

The error is pretty straight forward. The command
save can xzycbcr
is trying to save the variable "xzycbcr" into a file called "can.mat", but there is no variable called "xzycbcr". Maybe you are trying to save the variables "xz" and "ycbcr" and have left out a space, but I don't see those variables in your workspace since MATLAB is case sensitive.
Having a variable called YCBCR in a script called YCbCr is bound to cause you confusion.
