draw boundary conditions in matlab

To draw boundary conditions in Matlab, you can use the plot function to create a line plot of your data. The plot function takes in the x and y values of your data and plots them as a line. Here is an example that shows how to create a line plot of boundary conditions:

main.m
% Define x and y values
x = linspace(0, 1, 100);
y = sin(pi * x);

% Create line plot
plot(x, y, 'LineWidth', 2);

% Define colormap
cmap = colormap('cool');
colormap(cmap);

% Add colorbar and label
colorbar;
ylabel('Boundary Condition');

15 lines

This code will create a line plot of a sine wave defined by y = sin(pi * x) with x values from 0 to 1. The LineWidth parameter sets the thickness of the line. The colormap function defines a colormap to show the value of the boundary condition along the line. The colorbar function adds a colorbar to the plot to show the color scale, and the ylabel function adds a label to the colorbar.
