Matrix division "in scalar way"

Hello,

I have following formula

X=Y/(Z*2);

Where

Y is a vector predefined 1x200 - let say 1, 2, 3, 4, 5 .... 200

Z is also a vector predefined 1x200 - let say 1, 2, 3, 4, 5 .... 200

If I run it in sacalar I should always get 0.5 (1/(1*2) = 2/(2*2) =...= 200/(200*2)

I would like to get this same kind of results but stored in 1x200 array/vector when I run it as a matrix operation.

So X = [0,5 , 0,5 , .... 0,5]

How to do that?

If I run it like:

X=Y/(Z.*2);

I only get single result

and If I run it like:

X=Y\(Z*2);

I got a nonsense 200x200 matrix.

I will be thankful for any tips!

It is not nonsense, you just used the wrong operation:

Answer 1

[Alan Stevens]

X = Y ./ (Z .* 2);

Note the dot by the divide sign.

Read the link KSSV and Stephen Cobeldick links, by the way .* is simply *

Read about element by element operations in MATLAB. https://www.mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html#:~:text=Array%20operations%20execute%20element%20by%20element%20operations%20on%20corresponding%20elements,location%20in%20the%20second%20operand.

X=Y./(2*Z);
