Generate and return the Cumulative Distribution Function (CDF) of the ExpGamma distribution for an input x
within the support of the distribution \(x \in (\infty,+\infty)\).
See the documentation of pm_distExpGamma for more information on the ExpGamma CDF.
 Parameters

[in]  x  : The input scalar or array of the same shape as other array like arguments, of type real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128), containing the values at which the CDF must be computed.

[in]  kappa  : The input scalar or array of the same shape as other arraylike arguments, of the same type and kind as x , containing the shape parameter of the distribution.
(optional, default = 1. ) 
[in]  logSigma  : The input scalar or array of the same shape as other arraylike arguments, of the same type and kind as x , containing the location parameter of the distribution.
(optional, default = 1. ) 
 Returns
cdf
: The output scalar or array of the same shape as any input arraylike argument, of the same type and kind the input argument x
, containing the CDF of the distribution at the specified x
.

 Warning
 The condition
kappa > 0
must hold for the corresponding input arguments.
This condition is verified only if the library is built with the preprocessor macro CHECK_ENABLED=1
.

The
pure
procedure(s) documented herein become impure
when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1
.
By default, these procedures are pure
in release
build and impure
in debug
and testing
builds.
