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.

Sep 9, 2015 · The following function, function z_matmultiply(A,B) multiplies two three dimensional matrices which have the same depth. Dot multiplication is done in a manner that is as parallel as possible, thus you might want to check the speed of this function and compare it to others over a large number of repetitions.

In MATLAB, you can multiply two arrays element-wise using the `.*` operator to perform efficient mathematical operations on the corresponding elements of the arrays. Here's an example code snippet: A = [1, 2, 3; 4, 5, 6]; B = [7, 8, 9; 10, 11, 12]; C = A .*

In MATLAB, you can multiply matrices or arrays using the `` operator for matrix multiplication or the `.` operator for element-wise multiplication. Here's a code snippet for both types:

Oct 30, 2012 · I need to convolve a matrix-valued function (k) with a vector-valued function (X), each of which is defined on R^3. I need to to this in MATLAB, so naturally I will do the discretized version. I plan on representing k and X by 5- and 4-dimensional arrays, respectively.

Mar 25, 2017 · I tried to multiply elements of an array using all possible combinations. For example: A = [2,3,5] -> 2*3,3*5,5*2. How can this be done in MATLAB? nchoosek with prod is exactly what you're looking for. or Req=prod(nchoosek(A,2),2); as a one-liner.

Array multiplication in MATLAB involves performing operations on arrays of numbers. Element-wise multiplication is used when you want to multiply corresponding elements of two arrays together. This type of multiplication is denoted using the .* operator.

Multiply the matrices by using the element-wise multiplication operator .*. This operator multiplies each element of the first matrix by the corresponding element of the second matrix. The dimensions of the matrices must be the same.

The same concept applies here as well where the multiplication operator (*) multiplies the arrays using array, or matrix, multiplication and the dot multiplication operator (.*) multiplies each corresponding array value together, hence why the size must be the same for this.
