More precisely to move and rotate a point (vector x y z) with a transform matrix (4 by 4) you must add to the point a new component. This will make the point a vector x y z w; By setting w to be 1 and multiply the point * transform = transformed point in space; If the w = 0 then point * transform = only rotated point.

How do you multiply 4×4 matrices in C?
4×4 matrix multiplication. This is a simple C++ code with a function mult to multiply matrices. This can easily be generalized for any n × n matrix by replacing 4 with any positive number greater than 1. The multiplication is done by iterating over the rows, and iterating (nested in the rows iteration) over the columns.
How to multiply a matrix by another matrix?
A Matrix is an array of numbers: A Matrix. (This one has 2 Rows and 3 Columns) To multiply a matrix by a single number is easy: These are the calculations: We call the number ("2" in this case) a scalar, so this is called "scalar multiplication". But to multiply a matrix by another matrix we need to do the "dot product" of rows and columns ...
What are the conditions for matrix multiplication?
Read the instructions. The main condition of matrix multiplication is that the number of columns of the 1st matrix must equal to the number of rows of the 2nd one. As a result of multiplication you will get a new matrix that has the same quantity of rows as the 1st one has and the same quantity of columns as the 2nd one.

How to find the product of a matrix?
The product of a matrix is calculated by calculating the product sums of the pairs from the row vectors of the first matrix and the column vectors of the second matrix.
Can matrices represent simultaneous equations?
There is a special rule for multiplications of matrices constructed in such a way that that they can represent simultaneous equations using matrices.
How to multiply a matrix?
Matrices can be multiplied by a scalar value by multiplying each element in the matrix by the scalar. For example, given a matrix A and a scalar c:
How are matrices multiplied?
If the matrices are the correct sizes, and can be multiplied, matrices are multiplied by performing what is known as the dot product. The dot product involves multiplying the corresponding elements in the row of the first matrix, by that of the columns of the second matrix, and summing up the result, resulting in a single value. The dot product can only be performed on sequences of equal lengths. This is why the number of columns in the first matrix must match the number of rows of the second.
What is the dot product of a column in a matrix?
The dot product is performed for each row of A and each column of B until all combinations of the two are complete in order to find the value of the corresponding elements in matrix C. For example, when you perform the dot product of row 1 of A and column 1 of B, the result will be c1,1 of matrix C. The dot product of row 1 of A and column 2 of B will be c1,2 of matrix C, and so on, as shown in the example below:
How to determine the lower dimension matrix?
The elements of the lower-dimension matrix is determined by blocking out the row and column that the chosen scalar are a part of, and having the remaining elements comprise the lower dimension matrix. Refer to the example below for clarification.
How to add matrices to a matrix?
If the matrices are the same size, matrix addition is performed by adding the corresponding elements in the matrices. For example, given two matrices, A and B, with elements ai,j, and bi,j, the matrices are added by adding each element, then placing the result in a new matrix, C, in the corresponding position in the matrix:
