I have a matrix 'a' with size 3x3 and 'b' with size 3x1.i want to multiply the inverse of 'a' with matrix 'b'.I tried the below code but got an error "Matrix dimensions must agree". please help to solve this a=[1 0 -3; 2 -2 1; 0 -1 3]; ...
You want to do matrix multiplication with psi1 which, as explored above, might be 2 rows and 1 + length(t) columns. You could consider reshaping the Y, but unless you are trying to match up the dimension of length 2 and produce length(t) by (length(t)+1) as the output array, ...
How to solve for a variable in a matrix? How does a rotation matrix work? Let A be an n x m matrix and B an m x k matrix. Prove that If a matrix A is 5 x 3 and the product AB is 5 x 7, what is the size of B?
Show how to solve for x in a matrix. Prove that if A is a m x n matrix and B is a nxm matrix where m > n, then det(AB) = 0 . How do you do you multiply a 3 x 2 matrix by a 2 x 2 matrix? How do you multiply a 2 x 2 m...

A matrix is a table of values written in row and column form that represent one or more linear algebraic equations. There are many different ways to solve a matrix depending on whether you are given linear equations, and your instructed mathematical operation such as multiplication, addition, sub...
I have read two related posts. Someone pointed out that the element values of the constant matrix cannot beInfandNaN, and avoid dividing by the integer0during calculation. But in Matlab, matrix multiplication withInfelements is supported. How should I ...

When you transform one of these graphs, you shift it up, down, to the left, or to the right.Being able to visualize a transformation in your head and sketch it on paper is a valuable tool. Why? Sometimes the only way to solve a problem is to visualize the transformation in your ...
Inverse of matrixMathematically, the inverse of matrix is another matrix, which on multiplication with the given matrix gives the multiplicative identity. For a matrix A, its inverse is A-1, and A · A-1 = A-1· A = I, where I is the identity matrix. The matrix whose determinant is...
