Hi everyone
I am very new at awk but think that that might be the best strategy for this. I have a matrix very similar to a correlation matrix and in practical terms I need to convert it into a list containing the values from the matrix (one value per line) with the first field of the line (row... (5 Replies)

cexpl
CEXP(3) BSD Library Functions Manual CEXP(3) NAME
cexp -- complex exponential function SYNOPSIS
#include <complex.h> double complex cexp(double complex z); long double complex cexpl(long double complex z); float complex cexpf(float complex z); DESCRIPTION
cexp(z) returns the complex exponential of z. cexp(conj(z)) = conj(cexp(z)), for all complex floating-point numbers z. SPECIAL VALUES
The conjugate symmetry of cexp() is used to abbreviate the specification of special values. cexp(+-0 + 0i) returns 1 + 0i. cexp(x + inf i) returns NaN + NaN i, and raises the invalid flag, for finite x. cexp(x + NaN i) returns NaN + NaN i, for finite x. cexp(inf + 0i) returns inf + 0i. For the following two cases, cis(y) denotes cos(y) + I*sin(y). cexp(-inf + yi) returns 0*cis(y), for finite y. cexp(inf + yi) returns inf*cis(y), for finite nonzero y. cexp(-inf + inf i) returns -0 + 0i. cexp(inf + inf i) returns -inf + NaN i, and raises the invalid flag. cexp(-inf + NaN i) returns -0 + 0i. cexp(inf + NaN i) returns -inf + NaN i. cexp(NaN + 0i) returns NaN + 0i. cexp(NaN + yi) returns NaN + NaN i for all nonzero numbers y. cexp(NaN + NaN i) returns NaN + NaN i.
