inverse_binary.pro
Inverse function of the binary.pro function => given a
input array of 0/1, return its corresponding byte/integer/long
representation
inverse_binary
result = inverse_binary(binnumb)
Return value
A byte/integer/long array with (d1, d2...) dimensions
Parameters
binnumb
in
required
Must be a binary type array containing only 0 and 1.
According to binary.pro outputs, binnum array must have the
following dimensions values: (8, t, d1, d2...)
t gives the output type: t = 1 -> byte
t = 2 -> integer
t = 4 -> long
(d1, d2...) are the output dimensions
Examples
IDL> a=indgen(5)
IDL> b=binary(a)
IDL> help, b
B BYTE = Array[8, 2, 5]
IDL> print, b
