1. Matlab Tutorial Iman Moazzen First Session – September 11, 2013

2. Matlab (Matrix Laboratory) It allows you to solve many technical computing problems, especially those with vector or matrix formulation.

4. Identifiers Variables or function names Remarks: 1- It can include letters, digits, underline 2- The first character must be a letter e.g.: 3iman iman@3 iman613 iman$$ Iman613 iman_3 pi i j

5. Matlab (Matrix laboratory) Single value a=1 Vector row vector: a=[1 2,3] column vector a=[1;2;3] Matrix a=[1 2 3;4 5 6;7 8 9]

6. a=[1 4 6 7; 5 2 0 9; 8 8 3 2; 7 6 5 1] a(1,3)  6 a(1,:)  [1 4 6 7] a(:,2)  [4;2;8;6] a(1:3,2:3)  [4 6;2 0;8 3] 2D index: a(row,column) 1D index: a(index) start:step:end e.g: 1:2:5  [1 3 5]

7. 1D index a(1,2) a(6)  2 a(1:2:end)  [1 8 4 8 6 3 7 2]

8. Special Matrix eye  eye(3,3)  ones  ones(1,3)  [1 1 1] zeros  zeros(1,4)  [0 0 0 0] rand  rand(1,2)  [0.37 0.86] linspace  linspace(1,3,5)  [1 1.5 2 2.5 3]

9. Basic Fucntion + - * / ^ abs angle imag real conj round floor ceil mod min max sum prod cart2pol pol2cart syms subs exp log log10 log2 sqrt sin cos tan asin acos atan help

10. Use M.File to create Matlab code intead of command window file  new  M.file

11. Conditional Statements if-elesif-else while switch

12. Function function [out1,out2,…]=functionname(input1,input2,…) Note: function can not be run directly, you need to call it.

13. Graphing plot - color - style - Label
