Random matrix generator tool What is a random matrix generator?
This tool generates all kinds of random matrices and has over a dozen differnt options. You can change the matrix dimension by entering the number of rows and columns. You can separate matrix elements and rows with any character. You can set the range of minimum and maximum allowed random values. You can create the matrix using integer numbers or decimal numbers, and control the number of decimal number precision. Also, you can select various types of random matrices – you can generate fully filled (regular) matrices, diagonal matrices, upper and lower triangular matrices, and symmetric matrices. Finally, if necessary, you can improve the look of the random matrix by enabling prettify matrix option that will place all matrix elements in nice, evenly-spaced columns. Mathabulous!
Random matrix generator examples Click to use
Fully-filled Random Matrix
This example generates a regular rectangular matrix with 10 rows and 8 columns. All matrix elements are integers and belong to the range from 1 to 50. Also for a better view, we've enabled the prettify mode.

Create an Identity Matrix
This example generates a square 10 by 10 diagonal matrix (that is, all elements outside the main diagonal are zero). Since the minimum and maximum values equal to 1, we get the identity matrix. Not very random but very fun!

Upper Triangular Random Matrix
In this example we generate a random right triangular matrix (all elements below the main diagonal are zero). We choose to generate fractional numbers with 2 digits after the decimal point, and enable the prettify mode to have even columns.

Symmetric Random Binary Matrix
In this example we generate a random symmetric matrix with binary elements. To do it we set the value range from 0 to 1, and choose the symmetric matrix type.

Random Lower Triangular Matrix with Negative Values
This example creates a lower triangular matrix with random negative numbers. We set the random value range to be min=-100 and max=-1. This generates random values for this matrix from -100 to -1 (inclusive).
