## Questions about interfacing Matlab with AT89S51 (Assembly)

I want to interface matlab (GUI) with AT89S51 uC to control the direction and angle of a bi-polar stepper motor. How should I proceed? The questions that I have in my mind include: 1. Can I send the no. of steps first in one byte of data, then another byte of data containing the direction data (CW or CCW)? How can I do this? 2. How should (...)

## matlab assginment about antenna arrays

hey can anyone help me please iam doing a matlab assginment about antenna arrays and what i wrote so far is N=8; t=-2*pi:0.001:2*pi; l=1; d=l/2; b=2*pi/l; Y=b*d*cos(t); A=(sin(N*(Y/2))./(N*sin(Y/2))); plot(t,A); polar(t,A); and it works but i need some one who can help me in 3D part i cant find it so please (...)

## Matlab code antenna patterns (E,H components,co,cross,dir)

Hello, I have some measurement results of an antenna saved in a text file. There are 6 columns of data (1.theta angle, 2.phi angle, 3.module and 4.phase-for copolar component; and 5.module and 6.phase-for crosspolar component) What I want to do is plot the radiation diagrams for the (...)

## matlab graphs (polar,mesh,surf)

Search matlab help for "plot", "polar", "mesh", and "surf", and you will find good examples. Here's a simple example of subplots, and a few other adjustments: x = 0:30:360; y = ; subplot(1,2,1); plot(x,y); grid on; set(gca,'XTick',0:30:360'); xlim(); subplot(1,2,2); polar(x*pi/180,y); (...)

## Help me plot 3d polar antenna pattern in Matlab

Hi, I'm trying to plot 3d polar antenna pattern with matlab, but it doesn't work. The most I can do is to convert data to rectangular coordinates and then use mesh or surf. Obviously it's not the same. Does anybody know how can I do it (commercial software or private code)? thanks a lot Grendhell
