input	description	data type	value type	default value
A	input data	number, vector	variable
B	masker or threshold	number, vector	variable
C	replacement data	number, vector	variable
COND	condition	number (int.), string	variable	0
output	description	data type	value type	comment
Y	masked data	same type as A	variable

Description

If the condition defined by COND is true, C_i is assigned to Y_i, otherwise Y_i is set to A_i. If A is a vector, the inputs B and C can be numbers or vectors with the same length as A.

COND	Assignment
0 or <	Y i = { C i if  A i < B i A i otherwise {\displaystyle Y_{i}={\begin{cases}C_{i}&{\mbox{if }}A_{i}<B_{i}\\A_{i}&{\mbox{otherwise}}\end{cases}}} $Y_{i}={\begin{cases}C_{i}&{\mbox{if }}A_{i}<B_{i}\\A_{i}&{\mbox{otherwise}}\end{cases}}$
