This function takes a 1-D, slightly noisy test signal and fits 6 Gaussians to it with the fminsearch() function. The parameters (amplitude, peak location, and width) for each Gaussian are determined. The 6 Gaussians should sum together to give the best estimate of the original test signal. You can specify whatever number of Gaussians you like. Only basic MATLAB is required (no toolboxes).
