The second function inverts the corrected scattering to a particle size distribution. The
syntax is as follows:
The first argument is the corrected scattering ( cscat ) from the structure returned from
‘getscat_L200X.’ The following three argument are set to zero or one.
Random
– If set to 1, the randomly shaped particle matrix is used to invert the data. If set to
zero, the spherical particle matrix is used. See Appendix G: Spherical and Random Shape
Particle Models for more information.
Sharpen
– If set to 1, the function checks the width of the size distribution and increases the
number iterations if the size distribution is wide (recommended).
ShowProgressBar
– If set to 1, a progress bar will display the processing status.
The function will return the volume distribution in µL/L ( vd ) and the midpoint of each size bin
in microns ( dias ).
[vd, dias] = invert_L200X(Cscat,Random,Sharpen,ShowProgressBar)
