Hello,
I want to be able to cut and paste columns from two tables in one command.
Presently I do the following:
cut -f 1,3-6,9 table1.in > table1.out
cut -f 7,6,1-3 table2.in > table2.out
paste table1.out -d '\t' table2.out > MergedTable.out
Is there a better way to do this?

I am confused by the value of "currdisk->currangle" after adding operation. Initially the value of "currdisk->currangle" is 0.77500000000000013, but after adding operation, it's changed to "-nan(0x8000000000000)", Can anyone explain ? Thanks! The following is the occasion of gdb debugging.

CTANH(3) BSD Library Functions Manual CTANH(3) NAME
ctanh -- complex hyperbolic tangent function SYNOPSIS
double complex ctanh(double complex z); long double complex ctanhl(long double complex z); float complex ctanhf(float complex z); DESCRIPTION
ctanh(z) computes the hyperbolic tangent of the complex floating-point number z. For all complex floating point numbers z, ctanh(conj(z)) = conj(ctanh(z)), ctanh(-z) = -ctanh(z). SPECIAL VALUES
The symmetries of ctanh() are used to abbreviate the specification of special values. ctanh(0 + 0i) returns 0 + 0i. ctanh(0 + inf i) returns NaN + NaN i, and raises the invalid flag. ctanh(0 + NaN i) returns NaN + NaN i. ctanh(x + inf i) returns NaN + NaN i, and raises the invalid flag, for finite nonzero x. ctanh(x + NaN i) returns NaN + NaN i, for finite nonzero x. ctanh(inf + 0i) returns 1 + 0i. ctanh(inf + yi) returns 1 +- 0i, for finite positive y, with the sign chosen to match the sign of sin(2y). ctanh(inf + inf i) returns 1 + 0i. ctanh(inf + NaN i) returns 1 + 0i. ctanh(NaN + 0i) returns NaN + 0i. ctanh(NaN + yi) returns NaN + NaN i, for nonzero numbers y. ctanh(NaN + NaN i) returns NaN + NaN i.
