i have 2*1 cell array with size 242*234

and matrix of size 242*234

how to apply above code for it.

i am trying with this

Result=cellfun(@(x)x*matrix,Cell,'un',0)

then i get following error

Error in @(x)x*matrix

or if i try with

matrix=matrix.'

then it gives the out put of 242*242.

In my case i need 242*234 matrix.

please help me to solve this.

thanks in advance.

You may want to do element-wise (array) multiplication rather than matrix multiplication.

Try this:

@(x)x.*matrix

Note the (.*) element-wise multiplication operator.

See the documentation section on Array vs. Matrix Operations (link) for details.
