- sddsexpfit
`sddsexpfit`()sddsexpfit -- Does an exponential fit to column data. Example application: finding the exponential lifetime of a beam in a storage ring, or the half-life a radioactive sample. - sddsgenericfit
`sddsgenericfit`()sddsgenericfit -- Does generic fits to column data. Example application: fitting the sum of two gaussians. - sddsgfit
`sddsgfit`()sddsgfit -- Does gaussian fits to column data. Example application: finding the width of a resonance, or the rms size of a beam profile. - sddsmpfit
`sddsmpfit`()sddsmpfit -- Does polynomial fits to multiple columns data, including error analysis. Will do fits to specified orders, fits of specified symmetry, and adaptive fitting. Use`sddspfit`as a simpler and somewhat more capable alternative for fitting a single column of data. - sddspfit
`sddspfit`()sddspfit -- Does polynomial fits to column data, including error analysis. Will do fits to specified orders, fits of specified symmetry, and adaptive fitting.
