fun must be a binary (two-input) element-wise function of the form C = fun(A,B) that accepts arrays A and B with compatible sizes. For more information, see Compatible Array Sizes for Basic Operations. fun must support scalar expansion, such that if A or B is a scalar, then C is...
I got automatic offload running for MATLAB and was able to test matrix multiplication and some LAPACK functions running on the Phi. However, I was wondering if it was possible to run element-wise operations on the Phi, for example: A=rand(10000,10000); B=rand(10000,10000); C=A.*B; ...
Performing a small number of element-wise operations on a GPU is unlikely to speed up your code. For an example showing how arrayfun execution speed scales with input array size, see Improve Performance of Element-Wise MATLAB Functions on the GPU Using arrayfun. Use Function with Multiple Output...
The simplest case of CUDA®kernel creation is from MATLAB®functions that contain scalarized, element-wise math operations. When element-wise operations are enclosed within a for-loop body, concurrent CUDA threads can be invoked to compute each loop iteration in parallel. Because CUDA threads do...
Explicitly operating on a sub array and assign it back is a good approach. However, may I propose a bit of refactoring according to Matt Fig above:編
For more information, see Compatible Array Sizes for Basic Operations. Operands with an integer data type cannot be complex. Inputs that are tables or timetables must meet the following conditions: (since R2023a) If an input is a table or timetable, then all its variables must have data ...
