◆ minimizeZ0Error1D()

@function minimizeZ0Error1D

Tries to find a parameter that minimizes the error ( on Z0 ). This function only works with a single parameter. Calls calcAnalyze several times until the error is acceptable. While the error is unnacceptable, changes slightly the parameter.

This function does not change Z0 / Angl_L.

Parameters
avarParameter to synthesize
Returns
'true' if error < MAX_ERROR, else 'false'
