break

Purpose

Breaks out of a do or for loop.

Format

break;

Examples

x = rndn(4, 4);

/*
** Loop through each row of 'x' using 'r' as the loop
** counter
*/
for r(1, rows(x), 1);
   // For each row, loop through its elements
   for c(1, cols(x), 1);
      // Set the diagonal to 1
      if c == r;

         x[r, c] = 1;

      // Leave upper triangle as it is
      elseif c > r;

         // Terminate inner loop
         break;
      else;
         // Set lower triangle elements to 0
         x[r, c] = 0;
      endif;
   endfor;           /* break jumps to the statement after
                        this endfor */
endfor;

After running the code above, x should be a lower triangular matrix similar to below. Due to the use of random data, your matrix will have different non-zero elements above the diagonal.

1.000  1.288 -0.060  1.801
0.000  1.000  1.609  1.474
0.000  0.000  1.000 -0.768
0.000  0.000  0.000  1.000

Remarks

This command works just like in C.
