random vector generator

world's simplest number tool

Quickly generate random numeric vectors in your browser. To get your vector, just specify its length and element bounds you need in the options below, and this utility will generate that vector. Created by developers from team Browserling.

᠎᠎᠎          Tool Options

Vector Direction

Generate numbers horizontally
in a single row.
Generate numbers vertically
in a single column.

Vector Length and Interval

The number of vector elements.
Lower bound of vector elements.
Upper bound of vector elements.

Element Type and Delimiter

Number of digits after the
decimal point (accuracy).
Separate row vector numbers by
this symbol. (Comma by default.)

What is a random vector generator?

This is an online browser-based utility for generating vectors that have random numbers as its elements. A vector is a horizontal or vertical one-dimensional array of elements. A vector is also a matrix that has dimensions m×1 or 1×m. If the dimensions are m×1, then it's called a row vector (or a row matrix). If its dimensions are 1×m, then it's called a column vector (or a column matrix). The transpose operation turns a row vector into a column vector and vice versa. In this tool, you can generate a random vector of any length. You can set its upper and lower numeric bounds and then all vector elements will belong to this interval. You can also choose number type to generate – whole or fractional, and adjust the precision of the fractional part as needed. If you're creating row vectors then you can choose a character that will split the numbers. That's numberwang!


Random vector generator examples

A Random Column Vector

In this example, we generate a column vector of 10 elements. Each element is a positive random number from the interval 0 to 1000.

31 923 716 31 743 27 281 11 286 547
Required options
These options will be used automatically if you select this example.
Generate numbers vertically
in a single column.
The number of vector elements.
Lower bound of vector elements.
Upper bound of vector elements.

A Random Row Vector

In this example, we generate a row vector with fractional numbers as its elements. Each number has four digits of accuracy; the lower bound is -100 and the upper bound is 100. We create a vector with 15 coordinates and separate them with a semicolon character.

23.4752; -76.2368; 0.7985; 3.0629; -79.5424; 8.3210; -65.5598; -11.4074; -78.4643; 42.1829; 16.1060; -7.7733; -49.4257; 99.3338; -93.9263

Upper bound of vector elements.
Number of digits after the

Separate row vector numbers by
this symbol. (Comma by default.)

A Random Scalar

In this example, we generate a vector with the length of one. This is equivalent to a matrix with one row and one column. A 1x1 matrix or a vector with just one element is called a scalar. When generating this scalar, we require that it's an integer value from 1 to 1000000.
