function A=mysp2matsp(rowIdx,colIdx,entries)
%% transform three-arrays sparse matrix to matlab sparse matrix
nrow = size(rowIdx,2) - 1;
N = size(entries,2);
k = 1;
I = zeros;
J = zeros;
S = zeros;
for i = 1:nrow
j = rowIdx(i);
if i == nrow
for p = j:N
I(k) = i;
J(k) = colIdx(p);
S(k) = entries(p);
k = k + 1;
end
break;
end
for p = 1:(rowIdx(i+1)-rowIdx(i))
I(k) = i;
J(k) = colIdx(j);
S(k) = entries(j);
j = j + 1;
k = k + 1;
end
end
for i = N:-1:1
if S(i)==0
I(i) = [];
J(i) = [];
S(i) = [];
end
end
A=sparse(I,J,S);
end
error
Not enough input arguments.
Error in sparse2matrix (line 5)
N = size(entries,2);

When you ran the code, you only passed in either one parameter or else two parameters. You did not pass in three parameters.
We know that you passed in at least one parameter because you would have received the error about insufficient parameters on the line above there where you referred to rowIdx

YOu are trying to run the function without inputs........give required inputs and call the function.
