我假设您的意思是逐元素乘法:
I assume you mean element-wise multiplication:
使用 bsxfun :>
A = 10;
N = 4;
mat1 = randn(A,A);
mat2 = randn(A,A,N);
result = bsxfun(@times, mat1, mat2);
将bsxfun与 permute 对齐尺寸:
Use bsxfun with permute to align dimensions:
A = 10;
N = 4;
vec1 = rand(N,1);
mat2 = randn(A,A,N);
result = bsxfun(@times, permute(vec1,[2 3 1]), mat2);
