Master MATLAB Random Number Array Generation for Simulations and Data Analysis (rand randi randn)

Description:
In MATLAB, a random number array is an array of numbers generated by the rand, randi, or randn function, which produce uniformly distributed, integer, or normally distributed random numbers, respectively.

For example, the following code rounds the number 3.14159 to two decimal places:

round(3.14159,2)

The output of this code is 3.14.

Users can also specify the number of significant figures for rounding using the sigfig function. For example, the following code rounds the number 12345.6789 to three significant figures:


sigfig(12345.6789,3)

The output of this code is 12300.

Rounding functions can be useful in a variety of applications, such as scientific calculations and financial analysis.
