I need to divide two matrix with different rows and column

Hi Everyone,

I have two Matrix

A= 1x12

B=11x12

I want to divide D=A(of 1st element) / B(of complete Row)

now D should have 11 Rows which all divided by 1st element in A

Is it possible to do with for loop?

Thanks a lot..!

Your description asks for two different things.

"I want to divide D=A(of 1st element) / B(of complete Row)"

% Fake data
A = randi(20,1,12); 
B = randi(20,11,12); 
D = A(1,1)./B

"D should have 11 Rows which all divided by 1st element in A"

D  = B / A(1,1);

Or do you want to divide each column of A by the columns in B?

D = A ./ B;

This only calculates 1 row.

Please find my data in the attachement.

A is 1X12 B is 11X12

Each number of columns in A should be divided by B and the result should also be in 11X12

For example D should look like

7.2 (which is 36.1/5.19) 5,6(which is 33,33/5,88) ..................

7.16 (which is 36,1/5,04) 5,56(Which is 33,33/5,99) ....................

. .

. .

so on

The fake data I created fits your description. Check out the last line in my answer. It does what you're describing. Here's another example

D = [1 2 3] ./ [1 1 1; 2 2 2; 3 3 3];
