meshgridx - Script command

FDTD MODE DGTD CHARGE HEAT FEEM INTERCONNECT

Create a 2D meshgrid in the x direction

Syntax

Description

out = meshgridx(x,y);

If x and y are single column (or single row vectors), of dimension nX1 and mX1 respectively, the command

Will create a 2D matrix of dimension nXm where X(i,j)=x(i).

Examples

This example uses the image function to show the output of meshgrid. See the image function help for another example that uses meshgrid.

x=linspace(0,10,100);
y=linspace(0,10,10);
image(x,y,meshgridx(x,y),"x","y","meshgridx");
image(x,y,meshgridy(x,y),"x","y","meshgridy");

The following figures show the output of the the example code.

This example uses the mesh grid functions to create an image plot of a 2D gaussian function Z(x,y)=exp( -x^2-y^2).

x=linspace(-3,3,100); 
y=x; 
X=meshgridx(x,y); 
Y=meshgridy(x,y); 
Z=exp( -X^2 -Y^2); 
image(x,y,Z);
