Useful in practice !
There is an error in the statement of the problem: the matrix is the smallest that is compatible with the indices, and is not necessarily square.
how about including "regexp" in the forbidden commandlist?
"regexp" should be forbidden in this problem...ps:the forbidden is so powerful that I can put "zeros" word inside my function's comment.:lol
How about forbiding regexp?
I like it
In the problem, line 3 "square matrix" should have the "square" removed; plural of index will be indices... Nevertheless I like the problem especially with all those forbidden words.
funny
How can you iterate without a FOR loop?

Why this isn't working??
function B = name(value,row,col)
row=row';
col=col';
z=zeros(max(row),max(col));
[ro,~]=size(row);
for ii=1:ro
for jj=1
h=row(ii,jj);
b=col(ii,jj);
z(h,b)=value;
end
end
B=z;
end
%considering the linear mapping of matrix index
function B = your_fcn_name(value,row,col)
B = 0*rand(row(end),col(end));
temp = row'+(col'-1)*row(end);
B(temp) = value;
end

Nice challenge. Learned how matrix indices are used
I have completed upto creating zero matrix but can't find anything specific to insert the values! any hints?

function B = your_fcn_name(value,row,col)
B(row,col)=value;
end
but it shows error pls help me
When row and col are vectors of length n, B(row,col)=value resets all combinations of row(i) and col(j) (a total of n^2 elements); the problem wants just row(i) and col(i) (a total of n elements).
