Multiply each individual cell by a single matrix

I need to multiply each cell of a cell array by a single matrix, and store the result in the same size cell array.

I know how to do this with a for loop, but I was wondering if there was a faster/more efficient way?

For example:

Cell = {[1 2; 3 4; 5 6]; [7 8; 9 10; 11 12]};
matrix = [1 2; 3 4];

Then I would want Cell{1} * matrix stored in result{1}, Cell{2} * matrix stored in result{2}, so on and so forth till I get:

result = {[Cell{1} * matrix]; [Cell{2} * matrix]};
result = 
    {[7 10; 15 22; 23 34]; [31 46; 39 58; 47 70]}

Is it possible to perform this without a for loop?

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

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.

@Leela Sai Krishna, matrix multiplication with two matrices of size M x N that results in a matrix of size M x N is not algebraically possible unless M=N because the inner dimensions must agree.

If you want to do elementwise multiplication, so that

A.*B = [a11*b11 a12*b12 ... a1n*b1n;

a21*b21 a22*b22 .... a2n*b2n;

: : .. :

aM1*bM1 a*2M*b2M ... aNM*bNM]

Then you can use the "dot-multiply" operator with the same code snippet that @madhan ravi provided. In other words, include a period before the asterisk like this:

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