BesselI - Returns the modified Bessel function, which is equivalent to the Bessel function evaluated for purely imaginary arguments.

BesselJ - Returns the Bessel function.

BesselK - Returns the modified Bessel function, which is equivalent to the Bessel functions evaluated for purely imaginary arguments.

BesselY - Returns the Bessel function, which is also called the Weber function or the Neumann function.

Bin2Dec - Converts a binary number to decimal.

Bin2Hex - Converts a binary number to hexadecimal.

Bin2Oct - Converts a binary number to octal.

Complex - Converts real and imaginary coefficients into a complex number of the form x + yi or x + yj.

Convert - Converts a number from one measurement system to another. For example, Convert can translate a table of distances in miles to a table of distances in kilometers.

Dec2Bin - Converts a decimal number to binary.

Dec2Hex - Converts a decimal number to hexadecimal.

Dec2Oct - Converts a decimal number to octal.

Delta - Tests whether two values are equal. Returns 1 if number1 = number2; otherwise, returns 0.

Erf_Precise - Returns the error function integrated between zero and lower_limit.

ErfC_Precise - Returns the complementary error function integrated between the specified value and infinity.

GeStep - Returns 1 if number ≥ step; otherwise, returns 0 (zero). Use this function to filter a set of values. For example, by summing several GeStep functions, you calculate the count of values that exceed a threshold.

Hex2Bin - Converts a hexadecimal number to binary.
