MATLAB: How to create multiple parallel lines

lineMATLAB

How do I create parallel lines in a certain interval like in the picture? I am pretty sure I can use line() but I have not managed to understand how.

Plotting lots of lines is not the correct solution, you should use the grid command, or set the axes grid properties (e.g. adjust tick-mark positions, grid linestyle, grid color, grid transparency, etc.). The MATLAB documentation gives examples of how to adjust the grid lines:

https://www.mathworks.com/help/matlab/creating_plots/display-grid-lines-on-2-d-graph-1.html

This should get you started:

>> x = -10:0.1:10;
>> y = 100*sin(x);
>> plot(x,y,'-.')
>> ylim([-150,150])
>> set(gca,'YGrid','on') % Turn on the Y-grid. Also: color, linestyle, etc.

MATLAB: In MATLAB, is there a way to set the GRID at a spacing different from the ticks on the axes

Currently the ticks and grid line spacing are associated and so the only way to change grid spacing is to change the tick spacing. Here are some examples:

figure
plot(1:100)
set(gca,'xtick',[0:13:100])
set(gca,'ytick',linspace(0,100,13))
% The following code changes the minor grid 
% spacing by adjusting the tick spacing:
figure
plot(1:100);
grid on 
grid minor
set(gca,'xtick',[0:50:100])
set(gca,'ytick',[0:50:100])

MATLAB: How to show the major grid lines as solid and the minor grid lines as dotted

In order to change the style of the major gridlines, use the SET command as in the following example:

plot(1:10)
grid
set(gca,'gridlinestyle','-')
grid minor

This example will draw the major grid lines and change their style to solid (using the SET command for the axes GridLineStyle property) and then draw the minor grid lines without changing their linestyle.
