Many of the delivered functions fall into one of three categories: scalar-functions, vector-functions, or matrix-functions. The list below gives examples from each type of function, but is not all-inclusive.
abs exp floor round
cos sin tan ceil
sqrt real imag conj
isnan int
sum cumsum prod cumprod
mean max min fft
sort any all ifft
When using a vector oriented function, like max()
it
is possible to operate on matrix objects. For example the
maximum value in a matrix can be obtained via
max (max (a))
. The first call to max()
returns a vector of the maximum values from each column,
and the second call to max()
returns the maximum
value in the matrix.
