Error using * Inner matrix dimensions must agree. HELP

Hi,

kRba = linspace(1,10);

kRcb = linspace(1,10);

kRca = (kRba + kRcb);

I need kRca to vary as kRba and kRcb varies, i.e. when it runs through kRba = 4 and kRcb = 4 I need the kRca to equal 8. I'm trying to make a contour map. Is there anyway to do this? This is the full error -

Error using * Inner matrix dimensions must agree.

Error in three_body_system_one (line 15) T1 = mult * cos(kRca);

Any help would be really appreciated

Hi!

My guess: You write

T1 = mult * cos(kRca);

If mult and kRca have the same length and you want to multiply element-wise, you write

T1 = mult .* cos(kRca);

If this is not the solution, paste the code to reproduce the error.
