Execute block of code specified number of times



The general format is

The columns of the expression are stored one at a time in the variable while the following statements, up to the end, are executed.

In practice, the expression is almost always of the form scalar : scalar, in which case its columns are simply scalars.

The scope of the for statement is always terminated with a matching end.


Assume k has already been assigned a value. Create the Hilbert matrix, using zeros to preallocate the matrix to conserve memory:

Step s with increments of -0.1

Successively set e to the unit n-vectors:

The line

has the same effect as

except k is also set here.
