WebJul 18, 2024 · Matrix is a identity matrix. A matrix with only one row is called a row matrix or a row vector, and a matrix with only one column is called a column matrix or a column vector. Two matrices are equal if they have the same size and the corresponding entries are equal. We can perform arithmetic operations with matrices. WebA scalar is a number, like 3, -5, 0.368, etc, A vector is a list of numbers (can be in a row or column), A matrix is an array of numbers (one or more rows, one or more columns). In fact a vector is also a matrix! Because a matrix can have just one row or one column. So the rules that work for matrices also work for vectors.
