Matlab Guide J. Scholvin Matlab Guide for Device Characterization and Circuit Design Project This handout gives a very brief overview of useful matlab functions and code samples for handling weblab measurement data. If you have serious matlab trouble, send me an email with your code and error message(s). Simple syntax checking should be left to matlab , please :) 1. Matlab functions General reference at http://www.mathworks.com/access/helpdesk/help/techdoc/matlab.shtml Reference listing functions by category (very useful!!) http://www.mathworks.com/access/helpdesk/help/techdoc/ref/ref.shtml Functions you may find yourself using: clf; subplot(. ..); plot(. ..); semilogy(. ..); hold on; axis(. ..); sum(. ..) xlabel(. ..); ylabel(. ..); title(. ..); floor(. ..) orient . ..; Important: for multiplication and division, use the element by element operators .* and ./ * and / are matrix operators, which you don't want to use.

2. Code Samples 2.1. Reading the Weblab data file To read directly the CSV file from matlab without having to erase the first 3 lines, create a function in a file called readWeblabFile.m , with the following content: % returns a matrix from the weblab data-file <filename> function [data]=readWeblabFile(filename) fid=fopen(filename,'r'); data=[]; if (fid==-1) disp(['ERROR: file not found or could not be opened for read. check file ' filename]); break; end % skip first lines of comments
