how to assign value to a specific position in cell

11 views (last 30 days)
B= [1,1,0,1;0,1,1,1;1,0,1,1;0,1,1,0];
for i=1:numel(a)
A{a(i),b(i)}=[100 100 100 100];
Is there any other ways instead of using for loop?

if size(B,1) > size(A,1)
A(size(B,1),1) = {}; %extend A if needed
if size(B,2) > size(A,2)
A(1,size(B,2)) = {}; %extend A if needed
A(~B) = {[100 100 100 100]}; %replaces the find and the loop

You might be able to hide loops behind some cellfun() or arrayfun(), and abusing subsasgn() to do assignments using function call syntax...but otherwise, NO.
