Good evening
I can have a matrix with writing A(x,y)=..equation.. However, i have different equation and instead of changing script everytime i want to create script which can form a matrix from inputted equation. Although i tried some different codes, seems like i am walking away from what i want. Anyone can help me? You can see the current code below. Thanks
n=input('please enter n=')
eq1=input('please enter equation for creating A matrix=', 's')
A = zeros(n);
B =(n);
for y=1:n
B(y)=y;
for x=1:n
A(x,y)=inline(eq1,x,y);
end
end
A %matrix A
B %matrix B

Hello,
You might want to use MATLAB functions to achieve your objective.
For example,
function [A, B] = create_matrix(n, eq)
%your code
end
You can then create different matrices by passing different equations to the function.
Hope this helps.
