vsubc

vsubc

Conditional extraction of elements from the vector x.

Usage:

vsubc(x1,c,s1,x2)

vsubc(x1,c,s1,s2,x2)

Parameters:

x1

The input vector.

c

The condition. The following values are supported:

0 - select all x[i] where x[i] < s1

1 - select all x[i] where x[i] > s1

2 - select all x[i] where s1 < x[i] < s2

s1

A real number. See c for details.

s2

A real number (only used if c==2). See c for details.

x2

x2 is optional. If specified, the elements in x2 are extracted based on the selected values in x1. x2 must be a vector with exactly the same number of rows as x1.

Result:

The result is a scalar or a vector with the selected elements from x1 (or x2 - see x2 for details).
