I used both the command polyfit (Polynomial curve fitting) and Fit (Fit the curve). what is the difference between the two methods? Whit the second method I used 'normalize' but when I try to find the value with polyval the predicted data are no correct. How can I test the goodness ...
polyfit, polyval, interp1, interp2: These functions are used to fit polynomials, interpolate data, and perform other data analysis tasks. fft, ifft, conv, deconv: These functions are used to perform operations on signals such as fast Fourier transforms, convolution, and deconvolution. Linear alge...
then compute the statistics on N elements of the vector piecewise by reshape() to NxM columns, use the inbuilt MATLAB facility to compute by default over columns for builtin routines like mean and var or iterate over the M columns for those which haven't been vectorized...
MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. This allows you to solve many technical computing problems, especially those with matrix and vector formulations, in a fraction of the time it would take to write a program in a scalar noni...
What does this error message mean?For some reason the model is returning an imaginary component. I would contact tech support, that error message is useless.,
