How to find partial derivation for y with respect to x given y has a size of 3 by 300 and x has a size of 2 by 3?

x=rand(2,3);

y=rand(3,300);

Derivation=diff(y)./diff(x);

It didnt work.

Hi Bishwam,

To find partial derivative of (y) with respect to (x) in MATLAB, given that ( y ) is a ( 3 X 300 ) matrix and ( x ) is a ( 2 X 3 ) matrix, you can have a look at this example:

% Define symbolic variables
syms x1 x2 x3
y_sym = sym('y', [3, 300]);

% Example function f(x, y)
f = x1 * y_sym(1, :) + x2 * y_sym(2, :) + x3 * y_sym(3, :);

% Partial derivative of f with respect to x1
df_dx1 = diff(f, x1);

% Display the result
disp(df_dx1);

Adjust the function according to your requirements.

Hope this helps!
