Web30 okt. 2024 · I need to calculate the delay between the two vectors from the attached J.mat file. The first vector is J(:,1),J(:,2) and the second J(:,1),J(:,3). If you watch carefully there is a lag between the blue and the green vector, which are identical, except at the beginning, where there is a little difference between both. WebDescription. C = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array.

The behavior depends on the dimensionality of the tensors as follows: If both tensors are 1-dimensional, the dot product (scalar) is returned. If both arguments are 2-dimensional, the matrix-matrix product is returned.
