I have my function defined as:
function [x,y] = get_y(x)
if x<-1;
y=exp(x+1);
else
if (-1<x & x<5);
y=2+cos(pi*x);
else x>=5;
y=10*(x-5)+1;
end
end
end
when I individually run x=-2 or x=8, I get the correct answer.
When i run x=[-2,8], it only gives me answers based on the 3rd parameter. How do I get the correct output parameterized by the input?

You can use the same function which you provided, and use loop while calling the function, or you can modify the function to give output as per your input.
IDEA 1: Using the same code which you provided:
Calling the function:
input_array=[-2,8];
for index=1:length(input_array)
[a(index),b(index)]=get_y(input_array(index));
end
a
b
Function:
function [x,y] = get_y(x)
if x<-1;
y=exp(x+1);
else
if (-1<x & x<5);
y=2+cos(pi*x);
else x>=5;
y=10*(x-5)+1;
end
end
end
IDEA 2: You can prefer to nodify the function itself.
Calling the function:
[xx,yy]=get_y_advance(input_array);
xx
yy
Function:
function [x_array,y_array] = get_y_advance(input_array)
for index=1:length(input_array)
x=input_array(index);
if x<-1;
y=exp(x+1);
else
if (-1<x & x<5);
y=2+cos(pi*x);
else x>=5;
y=10*(x-5)+1;
end
end
x_array(index)=x;
y_array(index)=y;
end
end
