Change the value of independent variables to solve the dependent variable equation

17 views (last 30 days)
x=0:0.5:4*pi;
y=sin(x)+cos(x);
display(y);
In the above example the y(x) is given . Now i want to use y(Ax) in other equations (where A is some constant or variable) without hampering the original x values.
Please tell me how to do it.

Use function handle
x = 0:.1:10;
f = @(a) sin(a*x);
plot(x,f(2),'r')
line(x,f(5))

x=0:0.5:4*pi;
y=sin(x)+cos(x);
xi = x(2)*rand ;
yi = interp1(x,y,xi) ;
plot(x,y,'r',xi,yi,'*b')

Sir I wanted y(Ax) which means it will evaluate
sin(Ax)+cos(Ax)
I didnt ask for the interpolation of a certain value of x.
