Mourad Boufadene simulation of a nonlinear matrix AAA in Simulink without utilizing the Fcn block. Simulink provides several tools and techniques for implementing nonlinear systems and matrices in a structured way. Below is a step-by-step approach to guide you through the process:

Example:

Let us simulate the following nonlinear matrix:

A=[sin⁡(x)x2eycos⁡(y)].A = \begin{bmatrix} \sin(x) & x^2 \\ e^y & \cos(y) \end{bmatrix}.A=[sin(x)ey​x2cos(y)​].

• Step 1: Create input signals xxx and yyy using Constant or Signal Generator blocks.
• Step 2: Compute the elements:Use a Trigonometric Function block for sin⁡(x)\sin(x)sin(x) and cos⁡(y)\cos(y)cos(y). Use a Math Function block (set to square) for x2x^2x2. Use a Math Function block (set to exp) for eye^yey.
• Step 3: Combine these elements into a matrix using the Matrix Concatenate block.

By following this approach, you can successfully simulate nonlinear matrices in Simulink without relying on the Fcn block.

I hope this explanation provides clarity.
