How can I change a certain part of a graph to a certain constant value?

조회 수: 1(최근 30일)
For example, this is a sine graph.
x = linspace(0,2*pi,100);
y = sin(x);
How to change the value of y to be y = sin(0.2*pi) at x = 0.2*pi to 0.8*pi? so that the graph appears to be sine graph, except it is a horizontal straight line from x = 0.2*pi to 0.8*pi.
Thank you in advance.

Here is one way:
y(x>=0.2*pi & x<=0.8*pi) = sin(0.2*pi);
Note that I use inequalities because there are no values of x that are exactly 0.2*pi or 0.8*pi.
