field_contents - get the contents of the field

Calling Sequence

[header[,real[,imaginary]]]=field_contents(field_in)

Parameters

• field_in :input field. it must be diffractive wavefront.
• header : the header of the diffractive wavefront
• real : the real matrix of the field
• imaginary : the imaginary matrix of the field

Description

get get the contents of the field.it has three outputs: first is the header,the others are image (real and imaginary part) 2D matrix.

Examples

	F1=begin(0.01,1e-6);
	F2=gauss(F1,0.004);
	F3=forvard(F2,1);
	[h,r,i]=field_contents(F3);
	surf(r);
