which would be equivalent to the MATLAB m-code: C = zeros(2,6,4,5); for m=1:4 for n=1:5 C(:,:,m,n) = A(:,:,m,n) * B(:,:,m,n); end end The first two dimensions must conform using the standard matrix multiply rules taking the transa and transb pre-op...
这是通过分别编译一个执行矩阵乘法的cuda函数和一个将来自Matlab的数据输入读取到对象然后将它们链接在一起的mex函数来工作的。 Matlab对cuda一无所知,反之亦然。 包含的compile_matrix_multiply.m matlab函数将需要进行最少的编辑才能使其在常规Linux安装下运行,并且可能是Mac太硬了,我尚未对其进行测试。 该技巧原则...
When you say multiply the 9x9 by the 9x1, is that a matrix multiplication (which would output a 9x1), or is that an element-by-element multiplication producing 9 x 9 with each row in A multiplied the (single) value from the corresponding column in B ?
