Syntax
vis2d(scalar3d, normal_axis, intercept, [opts]) vis2d(scalar3d, normal_axis, intercept, obj_array, [opts]) vis2d(scalar3d, normal_axis, intercept, obj_array, src_array, [opts]) vis2d(scalar2d, [opts]) vis2d(scalar2d, obj_array, [opts]) vis2d(scalar2d, obj_array, src_array, [opts])
Description
vis2d(scalar3d, normal_axis, intercept) vizualizes a 2D slice of one of the x-, y-, z-components of the E- or H-field stored as an instance of Scalar3d. normal_axis is an instance of Axis the represents the axis normal to the slice, and intercept is the intercept of the slice on the normal axis.
vis2d(scalar2d) vizualizes a 2D slice stored as an instance of Scalar2d.
vis2d(..., obj_array) visualizes the objects in obj_array with the slice of a field. The elements of obj_array are instances of Object.
vis2d(..., obj_array, src_array) visualizes the objects and sources in obj_array and src_array with the slice of a field. The elements of src_array are instances of Source.
The optional argument opts is an options structure that controls the behavior of visualization. The fields of the structure are explained below. The default values of the fields are shown in brackets {}.
- opts.withgrid: true or {false} to show the grid or not.
- opts.withinterp: {true} or false to interpolate the field or not.
- opts.withpml: true or {false} to show the PML regions or not.
- opts.withabs: true or {false} to show the absolute values of the field or not.
- opts.cscale: positive value that controls the color bar range. Set to values less than 1.0 to saturate colors. The default value is 1.0.
- opts.cmax: another positive value that controls the color bar range; the positive maximum of the color bar range is cscale * cmax. If it is set to NaN, which is the default, then cscale * (maximum amplitude of the plotted data) is used for the maximum of the color bar range.
- opts.withcolorbar: {true} or false to show the colorbar or not.
- opts.withobjsrc: true or false to show the objects and sources or not. The default values is true when the number of objects is small (20), but false when the number of objects is large ( 20). To show only sources without objects, provide an empty obj_array in vis2d().
- opts.phase: additional phase angle phi. The field is visualized with an additional factor exp(i*phi) multiplied. Not useful if opts.withabs = true.
Example
[E, H, obj_array, src_array] = maxwell_run({ARGUMENTS});
opts.cscale = 5e-3;
opts.wihabs = true;
vis2d(E{Axis.y}, Axis.z, 0, obj_array, src_array, opts);
