exponential signal decoposition in 3d matrix in matlab

To decompose an exponential signal in a 3D matrix in MATLAB, you can first create the 3D matrix representing the time-frequency space of the signal. You can then multiply each element of the matrix by the desired exponential signal to decompose it.

Here is an example code snippet to decompose a 3D matrix using an exponential signal in MATLAB:

main.m
% Define the parameters of the exponential signal
A = 1;          % Amplitude
f = 0.1;        % Frequency
phi = 0;        % Phase shift

% Create a 3D matrix (for demonstration purpose)
[X, Y, Z] = meshgrid(1:100, 1:100, 1:100);
signal = cos(2*pi*f*Z + phi);  % Exponential signal (cosine in this case)

% Decompose the 3D matrix using the exponential signal
decomposed_signal = signal .* A;

% Display the result
disp(decomposed_signal);

In this code snippet, A, f, and phi are the parameters of the exponential signal. We then create a 3D matrix signal to represent the signal in a 3D space (here as a cosine signal). Finally, we multiply each element of the matrix by the amplitude A to decompose the signal.

You can adjust the parameters of the exponential signal and the 3D matrix to suit your specific decomposition requirements.
