Random matrix generator tool What is a random matrix generator?
This is an online browser-based utility for generating matrices with random numbers as their elements. You can generate random matrices of any size, shape, and form. All you need to do is enter the number of rows and columns in the options above as well as set the lowest and highest possible numeric values for random elements. You can also choose elements to be either integer or decimal numbers with the given precision. There are several templates for generating special types of matrices – 1) you can fill the matrix with random numbers only diagonally and generate a random diagonal matrix, 2) you can fill the matrix with random numbers above the diagonal and generate a random right-triangular matrix, 3) you can fill the matrix with random numbers below the diagonal and generate a left-triangular triangular matrix, 4) you can fill the matrix symmetrically and generate a random symmetric matrix, and 5) you can fill all matrix elements completely randomly. You can also customize matrix row and column separator symbols and if they're a space and a newline, then you can use beautify matrix function that aligns all matrix numbers into neat columns. That's numberwang!
Random matrix generator examples Click to use
Random Six-by-six Matrix
In this example, we generate a matrix with whole random numbers as its elements and dimension 6x6. All elements belong to the range from -100 to 100 and fill the entire matrix. The matrix is also prettified so all numbers are aligned below each other.
27 78 61 89 -66 68 -66 18 -73 67 -97 29 65 72 76 -15 32 38 -3 -94 100 -23 -21 -21 17 -40 -71 27 29 -5 93 -13 48 -15 8 80

Random Diagonal Matrix
This example fills a matrix with random numbers only on the diagonal. All other elements are zeros. This is done by selecting the diagonal matrix type in the options. The range of random values is 0-9, which means diagonal elements can be only 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
9 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 5 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 7 0 0 0 0 0 0 0 0 4 0 0 0 0 0 0 0 0 5 0 0 0 0 0 0 0 0 0

Random Right Triangular Matrix
This example generates a random upper triangular matrix (also known as right triangular matrix). This matrix has numbers only in the area above the main diagonal. We generate a matrix of fractions from the range [-5, 5], with three digits in the fractional part. As this matrix is rectangular (6x4), there are two zero rows under the main diagonal.
3.292 -1.541 1.776 -0.769 0 1.656 -4.467 0.979 0 0 4.721 -4.582 0 0 0 4.122 0 0 0 0 0 0 0 0

Random Left Triangular Matrix
In this example, we generate a lower triangular matrix (also known as left triangular matrix) of size 6 by 6. In this case, all numbers above the main diagonal are zero. We don't use the prettify matrix option here but instead, we split all rows of the matrix by a comma.
8, 0, 0, 0, 0, 0 46, 41, 0, 0, 0, 0 25, 19, 15, 0, 0, 0 14, 45, 11, 10, 0, 0 6, 35, 39, 46, 36, 0 48, 37, 2, 30, 49, 18

Random Negative Symmetric Matrix
This example creates a symmetric matrix, with random negative integers (from -10 to -1). A symmetric matrix has a property that element a_ij is equal to a_ji. Note that only a square matrix can be symmetrical, so we set the same number of rows and columns (equal to 4).
-1 -4 -3 -4 -4 -5 -2 -8 -3 -2 -7 -9 -4 -8 -9 -5

Random Vector
This example generates a matrix that is actually just a random vector. The randomness range is very tight here with the minimum value equal to 0.1 and the maximal value equal to 0.2. We set the numeric precision equal to 5 digits and generate a column matrix with eight elements.
0.12439 0.15987 0.10011 0.12835 0.13184 0.11571 0.18000 0.11669
