- 4. Command Window Workspace / Current Directory Command History Explore the Matlab Desktop
- 5. Matlab prompt assign operator suppress command output comment operator Try the same line without the semicolon and comments
- 10. square brackets to define matrices semicolon for next row in matrix
- 11. A = 3 2 1 5 1 0 2 1 7 indices of matrix element(s)
- 12. Try the following >> x=0:pi/12:2*pi; >> y=sin(x)
- 13. A = 3 2 1 5 1 0 2 1 7 What’ll happen if you type A(:,:) ?
- 14. A = 3 2 1 5 1 0 2 1 7 B = 1 3 1 4 9 5 2 7 2 Create matrices A and B and try out the the matrix operators in this slide Enter matrix B into the Matlab workspace
- 15. Matlab Desktop Press to create new m-file in the matlab editor
- 16. Highlight a few lines of your script by left- clicking and dragging the mouse over the lines. Right-click the highlighted lines and select Evaluate Selection. Will be slightly different in Linux
- 18. output inputfunction name for statement block function keyword help lines for function Access the comments of your Matlab functions >> help iterate Make sure you save changes to the m-file before you call the function!
- 19. Functions can have many outputs contained in a matrix Remember to use the Matlab help command for syntax >> help if if statement block
- 20. Method is linear >> i = 4 i = 16 i = 256 While statement block Switch statement block Without ; to print output
- 21. Click mouse on the left of the line of code to create a breakpoint local function workspace exit debug mode Debug menus
- 22. Investigate the function >> y=A*cos(w*t+phi); for different values of phi (eg: 0, pi/4, pi/3, pi/2), w (eg: 1, 2, 3, 4) and A (eg: 1, 0.5, 2). Use the hold on Matlab command to display your plots in the same figure. Remember to type hold off to go back to normal plotting mode. Try using different plot styles (help plot) A = amplitude phi = phase w = angular frequency = 2*pi*frequency Plot style
