G3 = gauss3D(sz_X, sz_Y, sz_Z, a, prec);returns a 3 dimensional matrix being a gaussian bell curve where the width in the (x/y/z)-dimension is proportional to 1/a(1), 1/a(2) and 1/a(3), respectively. "prec" is the data precision.Default is a=[2.5 2.5 2.5] and prec='double'Examples:Cubic-shaped...

clickfit_OH.m lets you mouse-click a series of datapoints on top of a (noisy) scatterplot and returns a spline or polynomial regression through the clicked dataseries. In addition the clicked series itself is returned.clickfit_OH.m uses an altered version of ginput.m (ginput_OH.m) that from the...

Two quaternary systems are studied: (1) Acetic Acid - Ethanol - Water- Ethyl Acetate and (2) Acetic Acid - Butanol - Water- Butyl Acetate. In these two systems, liquid phase esterification occurs. The residue curve map is computed using the UNIQUAC model and gas phase acetic acid dimerization....

How to fit a 2D Gaussian function to noisy data in Matlab? Or data with another number of dimensions and arbitrary fit function?It took me a while to find out how Matlab does this by the functions lsqcurvefit, fmincon or fminsearch. This project demonstrates how to use these functions to fit ND...
