Any attempt to use the data from R generates an error.

MATLAB Code on the GPU

GPU support is extended to include the following MATLAB code in functions called by

arrayfun to run on the GPU:

and

beta

betaln

int8

int16

intmax

intmin

ldivide

minus

not

plus

power

rdivide

realmax

realmin

times

uint8

uint16

Note the following enhancements and restrictions to some of these functions:

• plus, minus, ldivide, rdivide, power, times, and other arithmetic, comparison

or logical operator functions were previously supported only when called with their

operator symbol. Now they are supported in their functional form, so can be used as

direct argument inputs to arrayfun and bsxfun.

• arrayfun and bsxfun on the GPU now support the integer data types int8, uint8,

int16, and uint16.

The code in your function can now call any functions defined in your function file or on

the search path. You are no longer restricted to calling only those supported functions

listed in the table of Supported MATLAB Code.
