Hello all.
I have a grid of data points that range from 1:30 on the x axis in steps of 1, and .25:30 on the y axis in steps of .25, 3600 entries in total.
I need to find a way to store vectors from 5 selected points on the grid to the origin, and then from the origin to all 3600 points on the grid and store them.
How would I do this with a for loop?
Some guidance please?

What do mean, precisely, by "store a vector" ?
The coordinates of a vector to any point from the origin are just the values at that point and [0 0]

I'm assuming the idea is to store the distance between the points (specific selected points/all of them) and the origin. This can be done as follows using 'for' loops in MATLAB: for loops in MATLAB
distances = zeros(120,30);
for i = 1:30
x = i;
for j = 1:120
y = 0.25*j;
distances(j,i) = norm([x,y]);
end
end
