I must convert that for loop to while loop. How can I do that? I tried somethings but I couldn't get right result.
A=zeros(5,8);
[r,c]=size(A);
%for loop
for i=1:r % loops over rows
for j=1:c % loops over columns
if i>j
A(i,j)=4*i-2*j;
elseif i<=j
A(i,j)=i^2-3*j;
end
end
end
A

A=zeros(5,8);
[r,c]=size(A);
%for loop
i = 0 ;
while i<r % loops over rows
i = i+1 ;
j = 0 ;
while j<c % loops over columns
j = j+1 ;
if i>j
A(i,j)=4*i-2*j;
elseif i<=j
A(i,j)=i^2-3*j;
end
end
end

Other question is about exponential e. I submit it below. When I write code for while loop, I had to change a3 as 1 instead of 0. Nevertheless, I could get right result.
% a
% for loop k = 5
a3=0;
x=2;
k = 5
for n = 0:k
a3 = a3 + (x^n/factorial(n));
end
display(a3)
exp(2)
%while loop k = 5
a3=1;
x=2;
n=0;
k=5 % k = 5
while n<k
n = n+1;
a3 = a3 + (x^n/factorial(n));
end
display(a3)
exp(2)
