add two matrixes with different dimensions line by line

Hi,

Please some assistance with my following problem:

I am trying to add two matrixes that have diffent dimensions.

I have the following matrixes

• a = [2 3;1 3;2 4]
• PosPath =[ 1 -1;0 -1;-1 -1; 1 0; -1 0; 1 1; 0 1; -1 1];

and I want the outcome in Outcome as if [a(1,:)+Pospath ; a(2,:)+Pospath ;a(3,:)+Pospath]

I tried:

********************

for i=1:size(a,1)

c = a(i,:)+PosPath;

end

**********************

but this only captures the last statement (a(3,:)+Pospath).

So, my question is: What do I have to change to the code to get the matrix Outcome?

Thanks in advance!

Hello,

Have you tried what you want like this

Outcome = [a(1,:)+PosPath ; a(2,:)+PosPath ;a(3,:)+PosPath]

It is exactly what you mentioned before.

Hi Trung,

true, but... the the number of rows of 'a' can vary.

@Jaap It would be great, if you show us the addition of following two matrices

A=[1 2 3 4; 5 6 7 8];
B=[2 3 4;6 7 8;8 10 11];

Hello,

So, it coul be like that

clear 

a = [2 3;1 3;2 4] 
PosPath =[ 1 -1;0 -1;-1 -1; 1 0; -1 0; 1 1; 0 1; -1 1];
c = [];
for i=1:size(a,1)
 c = [c; a(i,:)+PosPath];
end
