Data masking / thresholding.

[SPU MASKABC A B SEL OUT Y]

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, Ci is assigned to Yi, otherwise Yi is set to Ai. 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 <
1 or >
2 or ≤
3 or ≥
