To create a 3D matrix in MATLAB, we can use the zeros() function to initialize the matrix with zeros. We can also create a 3D matrix by copying the contents of a 2D matrix into a new matrix with a third dimension of size 1.

MATLAB provides several built-in functions for creating 3D matrices: `rand`: Generates a matrix with random values. `zeros`: Creates a matrix filled with zeros. `ones`: Initializes a matrix filled with ones. Here’s how you can create a few examples: You can also manually define a …
