ISCTxx/IDCTxx/IICTxx/ICCTxx/IZCTxx Count selected vector elements
Name ISCTxx/IDCTxx/IICTxx/ICCTxx/IZCTxx
Count selected vector elements
Purpose Given a real, integer, or complex vector x of length n, these subprograms count
the number of elements of the vector that satisfy a specified relationship to a
given scalar a.
The last two characters of the subprogram name specify the relation of interest
between the elements of the vector and the scalar. For real and integer
subprograms, these characters, represented by “xx” in the prototype Fortran
statements, and the corresponding function values can be:
For complex subprograms, these characters and corresponding function values
are:
The vector can be stored in a one-dimensional array or in either a row or a
column of a two-dimensional array.
Usage VECLIB:
INTEGER*4 i, ISCTxx, n, incx
REAL*4 a, x(lenx)
i = ISCTxx(n, x, incx, a)
INTEGER*4 i, IDCTxx, n, incx
REAL*8 a, x(lenx)
i = IDCTxx(n, x, incx, a)
INTEGER*4 i, IICTxx, n, incx, a, x(lenx)
i = IICTxx(n, x, incx, a)
