new_swdft_cosreg function

Constructor function for class swdft_mod

new_swdft_cosreg(coefficients, fitted, residuals, data)

Arguments

• coefficients: matrix of coefficients for cosine regression model
• fitted: fitted values of cosine regression model
• residuals: residuals of cosine regression model
• data: original signal used to fit cosine regression

Returns

list with the following elements

• coefficients. A matrix of parameters, the three columns are: 1. amplitude 2. phase, and 3. frequency. There is only more that one row used when multiple frequencies are fit sequentially.
• fitted. fitted values of cosine regression model
• residuals. residuals of cosine regression model
• data. original signal used to fit cosine regression
