In Matlab, a matrix can be created simply by defining its elements within square brackets and separating the columns with commas and the rows with semicolons. Here is an example of a 2 by 3 matrix:

main.m25 chars3 lines

This creates a matrix `A`

with 2 rows and 3 columns, where the element in the first row and first column is 1, the element in the first row and second column is 2, and so on.

Matrices can also be created using built-in functions, such as `zeros`

and `ones`

. For example, to create a 4 by 4 matrix of zeros, the following command can be used:

main.m16 chars2 lines

This creates a matrix `B`

with 4 rows and 4 columns, where all the elements are 0.

Matlab also supports various operations on matrices, such as addition, multiplication, and inversion, making it a powerful tool for linear algebra and numerical analysis.
