NCERT … WebMar 9, 2024 · A matrix is an array of elements(usually numbers) that has a set number of rows and columns. An example of a matrix would be: A=(3−1021−1)A=\begin{pmatrix} 3 & -1 \\ 0 & 2\\ 1 & -1 \end{pmatrix}A=⎝⎛ 301 −12−1 ⎠⎞ Moreover, we say that a matrix has cells, or boxes, into which we write the elements of our array.
WebAn identity matrix would seem like it would have to be square. That is the only way to always have 1's on a diagonal- which is absolutely essential. However, a zero matrix could me mxn. Say you have O which is a 3x2 matrix, and multiply it times A, a 2x3 matrix. That is defined, and would give you a 3x3 O matrix.
