Problem 830. Fill a zeros matrix

The aim is to fill an array of all zeros given a numerical value and the index of row and columns for this value.

3 Inputs:

  • value : unique numerical value to fill the square zero matrix
  • row : index of row to fill
  • col : corresponding index of column to fill

1 Output:

- a matrix of same size which have for each row and col the value specified.

Example 1

Fill a 2*3 matrix with the value -13 for the line 2 and column 3 :

value = -13;
row = 2;
col = 3;

output B is:

B =  [0     0     0
      0     0   -13]

Example 2

value = 2012;
row = [ 2 3 3 5 ];
col = [ 1 1 4 4 ];

output B is

 B  =
             0           0           0           0
          2012           0           0           0
          2012           0           0        2012
             0           0           0           0
             0           0           0        2012

Restrictions

Sorry, as usual I want to make this problem a little bit harder: The following commands are forbidden: zeros, for, repmat, ones, while, and sparse.
