**Matrix class using vector C++ Forum**

Vectors In MATLAB a vector is a matrix with either one row or one column. The distinction between row vectors and column vectors is essential. Many programming errors are caused by using a row vector where a column vector is required, and vice versa. MATLAB vectors are used in many situations, e.g., creating x-y plots, that do not fall under the rubric of linear algebra. In these contexts a... A very common way of storing data is in a matrix, which is basically a two-way generalization of a vector. Instead of a single index, we can use two indexes, one representing a row and the second representing a …

**data structures A proper way to create a matrix in c++**

I want to create an adjacency matrix for a graph. Since I read it is not safe to use arrays of the form matrix[x][y] because they don't check for range, I decided to use the vector template class of the stl....Here is a little C++ program that creates an integer matrix as a vector of vectors of integers (std::vector

## How To Create A Matrix Using Vector In C

### matrix3 is a user defined data type and C++ gives you a lot of freedom to make it the way you want. However, if you make it overly complicated people cannot use it effectively.

- We are using templates and typdefs to make Vec be the name of a vector class with vector components made from doubles. And we are defining Mat to be a vector the components of which are themselves doube-precision vectors.
- For matrix multiplication C=AxB where total number of columns of matrix A should be equal to total number of rows of matrix B. For multiply a row vector to matrix is possible. For this number of elements of row vector should be equal to total number of rows of a matrix.
- @PatrizioBertoni: I prefer the second, obviously. There's a cute trick for storing an arbitrary n-dimensional matrix M as two 1-dimensional arrays, c (coefficients) and x (actual elements).
