The for Statement

The assignment expression in the for statement works a bit differently than Octave’s normal assignment statement. Instead of assigning the complete result of the expression, it assigns each column of the expression to var in turn. If expression is a range, a row vector, or a scalar, the value of var will be a scalar each time the loop body is executed. If var is a column vector or a matrix, var will be a column vector each time the loop body is executed. The following example shows another way to create a vector containing the first ten elements of the Fibonacci sequence, this time using the for statement: The assignment expression in the for statement works a bit differently than Octave’s normal assignment statement.
