how to convert from functions to matrix?

I hope to make matrix about functions such as y=sinx

In other words, y=sinx functions' graph will be corresponded to m x n matrix.

For example, when I have a 300 x 200 matrix with a origin of (150,1), I want to call the value of the path through which the sin function passes in this matrix one.

how to do it?

Thanks

If x is a matrix....then y = sin(x) will give you matrix as output...what you want?

Doesn’t make any sense?

i mean that i want to project each point on the graph from a 300x200 zeros matrix.

Let the origin is (150,1). So the value of this point will be one. Next, (151,2) will be one, ...

Are you trying to do something like this

M = zeros(300, 500);
cols = 1:size(M,2);
rows = floor(150-100*sin(cols/10));

idx = sub2ind(size(M), rows, cols);
M(idx) = 1;
imshow(M)
