Scientific functions

The following functions come in two forms. They either take a single matrix (FMat or DMat) argument and return a (respectively) FMat or DMat result, or they accept two (equal-sized) FMat or DMat arguments, apply the function to the first and store the results in the second matrix.

• abs
• exp
• sqrt
• ln
• log10
• log1p
• cos
• sin
• tan
• cosh
• sinh
• tanh
• acos
• asin
• atan

• asinh
• erf
• erfinv
• erfc
• erfcinv
• normcdf
• norminv
• gamma
• gammaln
• ceil
• floor
• round
• trunc

The following functions take two real FMat or DMat arguments and return a single FMat or DMat result. Or, if provided with three equal-sized FMat or DMat arguments, they apply the function to the first two matrices and store the results in the third.

• atan2
• pow
