Free online identity matrix generator. Just set the matrix size in the options and you'll automatically get a unit matrix of this dimension in the output form below. There are no ads, popups or nonsense – just a unit matrix generator. Created by math nerds from team Browserling.
This tool generates identity matrices of any size. A matrix is called an identity matrix (also known as unit matrix) if each element a_ij, where i = j, is equal to one, and each element a_ij, where i ≠ j, is equal to zero (i corresponds to the row number, j corresponds to the column number). The identity matrix is always a square matrix and has a dimensions of nxn. In this tool you can change the matrix dimension by specifying 'n' in the options. You can also customize the formatting of the matrix by selecting characters that separate elements and rows. Mathabulous!
This example generates a unit matrix of the twelfth order. That is, there are 12 ones on the diagonal (and all other elements are zero.)
In this example, we create a third-order (3x3) identity matrix using the dot symbol to separate elements and three asterisks to separate the rows.
Here's a fun example - we set the size of the matrix to be one and that generates just a single element matrix, which is just one.
You can pass options to this tool using their codes as query arguments and it will automatically compute output. To get the code of an option, just hover over its icon. Here's how to type it in your browser's address bar. Click to try!
