Create square marix of values for a 2 variable function.
显示 更早的评论
Hello,
I have a two variable function for a given domain i.e. f(x,y) for 0<x<100, 0<y<100 and x and y are discretized I want to form a square matrix where in the columns x remains constant and y varies or vices-versa. I have used the function command to create my function but I am struggling in the next part.
x= 0:0.01:100; y= 0:0.01:100;
function f = f(x,y)
f = cos(x)+sin(y);
end
采纳的回答
x= 0:0.01:100; y=(0:0.01:100)';
f=cos(x)+sin(y)

There is no tilde in the code I posted for you, I don't think...
Apostrophe means "transposed". So you "add" an (1xn) and an (nx1) vector in the above code. In MATLAB, by implicit expansion, this gives an (nxn) matrix.
Example:
x = [1 2];
y = [7;4];
x + y
[1+7 2+7;
1+4 2+4]
