compare elements of a matrix

Hi,

I want to compare each element of matrix with 'total 'and check if it is equal.

Code gives error. How can I do that please?

clc

clear

b=[2 2]

t=[1 1 ; 1 1]

total=2;

for v=1:b(1)

rowsum(v,1)=sum(t(v,:));

end

for y=1:b(2)

colsum(v,1)=sum(t(:,v));

end

if rowsum(:,1)==total && colsum(:,1)==total

disp 'yes'

end

No loops needed:

if all(sum(t)==total)
disp('Yes')
end
if all(sum(t,2)==total)
disp('Yes')
end

Thank you, what is the purpose of using 'all' ? If I am not mistaken, it also works without 'all'.

[madhan ravi]

all() is appropriate here because we check that each row or column sum equals to total. https://in.mathworks.com/help/matlab/ref/all.html?searchHighlight=All&s_tid=doc_srchtitle - read it

Thank you so much, I learned new things, all() and any() will be very useful.
