storing values from a for loop

clc;

clear all;

close all;

for k=-2:0.5:2

    x=k;

    x(k)=x;

end

I have to store values of x from -2 to 2 at a gap of 0.5 in a row vector but when I run this code I am getting an error as:

'Subscript indices must either be real positive integers or logicals.' Please tell me why am I getting this and how can it be corrected? how can I make the row vector?

Is this what you had in mind?:

myValues = -2:0.5:2;
myX = zeros(length(myValues),1);
for i = 1:length(myValues)
    
    myX(i) = myValues(i);
    
end

Thanks...it's working...My job is done....but please tell me why that error is there and can't it be corrected..

[Von Duesenberg]

Among other things, you asked Matlab to store a value in "slot" -2 of array x. The first "slot" in an array is 1. I'm deliberately using a somewhat loose terminology because I don't know what your background is and everyday words might be clearer.

(My edit of the answer was just to add indentation within the i-loop).
