mfun

Numeric evaluation of special mathematical function

Syntax

mfun('function',par1,par2,par3,par4)

Description

mfun('function',par1,par2,par3,par4) numerically evaluates one of the special mathematical functions listed in Syntax and Definitions of mfun Special Functions. Each par argument is a numeric quantity corresponding to a parameter for function. You can use up to four parameters. The last parameter specified can be a matrix, usually corresponding to X. The dimensions of all other parameters depend on the specifications for function. You can access parameter information for mfun functions in Syntax and Definitions of mfun Special Functions.

MuPAD® software evaluates function using 16-digit accuracy. Each element of the result is a MATLAB® numeric quantity. Any singularity in function is returned as NaN.

Examples

Evaluate the Fresnel cosine integral:

mfun('FresnelC',0:4)
ans =
         0    0.7799    0.4883    0.6057    0.4984

Evaluate the hyperbolic cosine integral:

mfun('Chi',[3*i 0])
ans =
0.1196 + 1.5708i   NaN
