w ∈ r^(p+1), x ∈ r^(n*p) en y ∈ r^n in matlab

To create the variables w, x, and y with the specified dimensions, you can follow the steps below in MATLAB:

1. Define the dimensions of the variables p and n based on your problem requirements.
2. Create variable w as a column vector with dimensions (p+1) x 1. This can be done using the zeros function.
3. Create variable x as a matrix with dimensions n x p. Again, you can use the zeros function.
4. Create variable y as a column vector with dimensions n x 1. Use the zeros function to initialize it.

Here is an example MATLAB code snippet that demonstrates these steps:

main.m
% Step 1: Define the dimensions
p = 3;  % Example value, replace with your desired value
n = 2;  % Example value, replace with your desired value

% Step 2: Create w
w = zeros(p+1, 1);  % (p+1) x 1 column vector

% Step 3: Create x
x = zeros(n, p);  % n x p matrix

% Step 4: Create y
y = zeros(n, 1);  % n x 1 column vector

In this code, w is a column vector of size (p+1) x 1, x is a matrix of size n x p, and y is a column vector of size n x 1. You can replace p and n with your desired values based on your problem requirements. You can access and manipulate elements of these variables using indexing and perform matrix operations as needed in MATLAB.
