How to combining outputs into one array?

Hello everyone,

I am a newbie to Matlab and I am struggling. I'm hoping that the output Y will turn out as:

Y = 74.48 80.87 84.06 89.53 92.79 94.82 96.16 97.07

BUT, my code outputs Y separately, one at a time.

MY CODE:

Y = [];
for X = [40,46,50,60,70,80,90,100]
    Y = 100*X.^2.65/(X.^2.65+26.7^2.65)
end

Can someone PLEASE help me.

Thank you!

When you are iterating over values that are not simple consequative integers starting from 1, then it is often a good idea to create a list of values to be processed, and then iterate an index over 1 to the size of the list, extracting the relevant entry of the list to use in the computations.

Y = [];
Xvals = [40,46,50,60,70,80,90,100];
Y = zeros(size(Xvals));
for K = 1 : numel(Xvals);
    X = Xvals(K);
    Y(K) = 100*X.^2.65/(X.^2.65+26.7^2.65);
end

Y

Y = 1×8

74.4820 80.8693 84.0574 89.5262 92.7852 94.8241 96.1585 97.0669

Rather than using a loop, the simpler MATLAB approach:

X = [40,46,50,60,70,80,90,100];
Y = 100*X.^2.65./(X.^2.65+26.7^2.65)

Y = 1×8

74.4820 80.8693 84.0574 89.5262 92.7852 94.8241 96.1585 97.0669
