Full Discussion: Averaging each row with null values
Top Forums Shell Programming and Scripting Averaging each row with null values Post 302612025 by ida1215 on Saturday 24th of March 2012 09:01:11 AM

Hi I'm sorry again, I have come across another problem with the computation of the mean for my data. On top of having entire rows equal null values (NaN), the data has also entire rows with valid values equal to 0 and so I'm having fatal error on division by zero. How to revise the code such that if entire row has values of NaN and zero, it will print NaN and 0, respectively.

Many many thanks.

casinh

CASINH(3)						   BSD Library Functions Manual 						 CASINH(3)

NAME

     casinh -- complex inverse hyperbolic sine function

SYNOPSIS

     double complex
     casinh(double complex z);

     long double complex
     casinhl(long double complex z);

     float complex
     casinhf(float complex z);

DESCRIPTION

     casinh(z) computes the inverse hyperbolic sine of the complex floating-point number z, with branch cuts outside the interval [-i, i] along
     the imaginary axis.

     casinh() returns values in a strip of the complex plane with imaginary part in the interval [-Pi/2, Pi/2].

     For all complex floating point numbers z,

	   casinh(conj(z)) = conj(casinh(z)).
	   casinh(-z) = -casinh(z)

SPECIAL VALUES

     The symmetries of casinh() are used to abbreviate the specification of special values.

     casinh(0 + 0i) returns 0 + 0 i.

     casinh(x + inf i) returns inf + Pi/2 i, for finite positive-signed x.

     casinh(x + NaN i) returns NaN + NaN i, for finite x.

     casinh(inf + yi) returns inf + 0i, for finite positive-signed y.

     casinh(inf + inf i) returns inf + Pi/4 i.

     casinh(inf + NaN i) returns inf + NaN i.

     casinh(NaN + 0i) returns NaN + 0i.

     casinh(NaN + yi) returns NaN + NaN i, for finite y.

     casinh(NaN + inf i) returns inf + NaN i.

     casinh(NaN + NaN i) returns NaN + NaN i.

NOTES

SEE ALSO

STANDARDS

     The casinh() function conforms to ISO/IEC 9899:2011.
