multiply/divide two cells array

Question

0 个投票

I have two cell arrays that have the exact same amount of elements

A: cell 1: [2, 5, 8, 9]
   cell 2: [ 5, 7, 3] 
   cell 3: [ 5, 3] 
B: cell 1: [ 1 ,8, 6, 3]
   cell 2: [ 4, 2, 7]
   cell 3: [ 8, 9]

I want to multiply each element of A by B, (cell 1= [2 40 48 27] ) so I get a new cell array C

I have this

C= cellfun(@x, A(x)*B(x), 'UniformOutput',false)

Thanks!

Hi, you need a 2 input function:

C= cellfun(@(x,y) x*y, A,B, 'UniformOutput',false)

Alternatively:

C = num2cell(cell2mat(A).*cell2mat(B))

I hope this helps

It should be a dot product:

C= cellfun(@(x,y) x.*y, A,B, 'UniformOutput',false)

You'are right. I though it was a a cell array with single double elements.
