.Wavelet.Examples.fileDataMRA

Information

This function carries out the complete wavelet MRA with graphic user interface. The data to be analyzed are to be read from the *.MAT data file that is generated by Dymola. Please note that only the wavelets of types 1, 2 and 3 are possible for MRA. Otherwise running errors will occur. The results are displayed with multiple curves. It is possible to show either the wavelet coefficients at different levels or the signals that are reconstructed with the coefficients of different single levels.

Since simple default values are provided with this function, a direct execution of this function without any extra input parameters will deliver a complete MRA analysis for an example.

Refer to the description of Families for detailed information about the available wavelets.
