create_field - create a field or diffractive wavefront.

Calling Sequence

[field_out]=create_field(header,real,imaginary[,real_image])

Parameters

• header :the header of the field.
• real :the amplitude (or real) matrix of the field
• imaginary :the phase (or imaginary) matrix of the field.
• real_image : a bool value. if ture, denotes the input data matrix are real and imaginary parts of the field, else they are amplitude and phase. the defaults is fause (e.g. 0)
• field_out : the output field or diffractive wavefront.

Description

another method to create a field or diffractive wavefront besides begin .

Examples

	f1=begin(0.01,1e-6);
	f2=gauss(f1,0.004);
	f3=forvard(f2,1);
	[h,r,i]=field_contents(f3);
	f=create_field(h,r,i,1);
	field_plot(f);
