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
