how to unnormalize data in matlab

To unnormalize data in Matlab, follow these steps:

1. Load the normalized data and the corresponding scaling factors that were used for normalization.
2. Create a function that applies the inverse scaling operation to the normalized data using the scaling factors.
3. Apply the function to the normalized data.

Here's an example code:

main.m
% Example normalized data
norm_data = [0.1, 0.5, 0.8];

% Example scaling factors
max_val = 100;
min_val = 0;

% Function to unnormalize data
function unnormalized = unnormalize_data(data, max_val, min_val)
    unnormalized = data .* (max_val - min_val) + min_val;
end

% Apply inverse scaling operation to normalized data
unnormalized_data = unnormalize_data(norm_data, max_val, min_val);

% Display unnormalized data
disp(unnormalized_data);

In this example, the unnormalize_data function applies the inverse scaling operation to the normalized data using the scaling factors max_val and min_val. The function returns the unnormalized data, which is then displayed using the disp function.
