exe-less-than

Purpose

Tests element-by-element less than, returning a matrix of results.

Format

y = a .< b

Parameters

param a:

Left operand.

type a:

matrix, vector, or scalar

param b:

Right operand.

type b:

matrix, vector, or scalar

Returns

return y:

Matrix of 1’s and 0’s indicating element-wise comparison results.

rtype y:

matrix

Examples

a = { 1, 5, 3 };
b = { 4, 5, 6 };
y = a .< b;

y =    1.0000000
       0.0000000
       1.0000000

Filtering Data

x = { 1, 5, 3, 8, 2, 9 };
mask = x .< 5;

mask =    1.0000000
          0.0000000
          1.0000000
          0.0000000
          1.0000000
          0.0000000

Remarks

• Returns a matrix with the same dimensions as the inputs.

• For scalar result (all comparisons true), use <.
