How to plot an equation with different parameter value?

x = 0:0.01:+10;
c = 1;
Y = (1-x.^2).^c;
plot(x,Y); hold on;
c = 1.1;
Y = (1-x.^2).^c;
plot(x,Y); hold on;

c=1.4;
Y = (1-x.^2).^c;
plot(x,Y); hold on;

Warning: Imaginary parts of complex X and/or Y arguments ignored.

c=0.3;
Y = (1-x.^2).^c;
plot(x,Y)

I am sure there is a concise way to do this same thing. I want to plot the equation y = (1-x^2)^c for c = [1, 1.1, 1.4, 0.3]. How to achieve that? In general how to plot an equation with varying parameter value chosen from an array?

It's correct as you proceed. But for Y to be real, x must be in [-1:1].

Try this —

x = 0:0.01:+10;
c = [1;1.1;1.4;0.3];
Y = (1-x.^2).^c;

figure
plot(x,Y)

legend(compose('c = %.1f',c), 'Location','best')

With‘c’ a vector, this can be done in one step. The legend is even easier to create!
