the determining factor is very significant. How can we use the above source to derive the formula for determining the determinant? In any linear algebraic number, I will omit it. The formula is as follows: For N x n matrix, Det (A) = A11 (when n = 1) Det (A) = A11 * A11 + A12 * A12 +... + A1N * A1N (when n> 1) Among them, a1j = (-1) 1 + J power * DETA (m1j) (where j = 1,..., n) It is the remainder of th

"C and Pointers" chapter 8th programming exercises 4th:Modify the Identity_matrix function in the previous question, which can be extended to an array to accept arbitrary-sized matrix parameters. The 1th parameter of the function should be an integer pointer, and you need a 2nd parameter to specify the size of the matrix.1 /*2 * * Determine if a matrix is a unit

When the plane is set to (NX,NY,NZ,D), the column main sequence reflection matrix with this planar mirror is as follows:The derivation is as follows:One, the expression of the platform:, over point P, the plane of the normal vector n, can be expressed as:Np+d=0where D is the forward distance from the plane to the origin point. If the plane faces the origin, D is positive and D is negative if the plane is back to the origin point.So the plane can be re
