Okay lets try to break it down here:
1) I have to create a 100 x 100 matrix
Create an all zero matrix like this:
A=zeros(100,100)
2) I have a formula in which the value K is defined as the greater value of i and j
Pretty sure this is what you must have in mind:
if i>j
k=i
else
k=j
end
3) compares the row and column position values and chooses the larger of the two, then defines that as the variable K
So you have to check all the values in the matrix A for above condition. You can do this easily by nested loops like this:
for i=1:100
for j=1:100
%Do your check here
end
end
Finally your code should look something like this:
A=zeros(100,100)
for i=1:100
for j=1:100
if i>j
k=i
else
k=j
end
A(i,j)=k;
end
end
Is this what you are looking for?
