### In maths C is a second order dominance matrix the same as a second order ranking?

No. To find the second-order ranking (second-order dominance vector, V2), you add each of the columns and it will give you a (how ever many rows) x 1 matrix.

for(int i=0;i

### What is matrix in maths?

It is a table of items, usually numbers. For example, you might consider the prices of several items in a shop. Put these in a column. Then for the same items in a different shop, another column alongside the first. And several shops. You finish up with an array of prices. That is an example of a matrix.

### What does determine mean in maths?

In Algebra, the word determinant is a special number which is associated to any square matrix. Like for example, a rectangular array of numbers where the finite number of rows and columns are equal. Therefore, the meaning of a determinant is a scale factor for measuring wherever the matrix is regarded.

### What does transpose mean in math?

Transpose means swap places. In maths, the term is usually used for matrices. It means truning the matrix around so that its rows become columns and columns become rows.
