Hi all,
I have a figure like this which was obtained by numerical solution. I want to use different color for different segments. Can anyone please help?

The figure already have different colors right? What data you have to plot? YOu need to use plot with different colors options. Read about plot.

In MATLAB, any one "primitive line object" is restricted to being a single color. If you want multiple colors, then you need to draw multiple lines -- or you need to take a very different approach such as drawing a surface or patch with face colors turned of and edge colors specified; for example see https://www.mathworks.com/matlabcentral/fileexchange/19476-colored-line-or-scatter-plot

For example, if index1, index2, index3, and index4 are in order:
plot(x(index1:index4), y(index1:index4), 'b-', 'LineWidth', 4);
hold on;
plot(x(index2:index3), y(index2:index3), 'r-', 'LineWidth', 4);
This will plot a blue line with a red portion in the middle.

There is no other way. "primitive line objects" can never have multiple colors for one line, so you need to use multiple lines or you need to use a different kind of graphics object.
