Conditional Coding

[Kami_Munchkins]

I want it to set variable g depending on whether it is a sin, sawtooth or cos. I though i should set it dependent on the input on variable x, however i can't seem to get it to work... I am very new to coding, self taught and would appreciate any help

clear all;
close all;
clc;
A = 3;
phi = 90;
f1 = 0.5;
SampleRate = 40000;
t1=-2*pi:pi/SampleRate:2*pi;
x = input('name');
if  x == sin
     g = A*sin(2*pi*f1*t1+phi);
elseif x == cos;
        g = A*cos(2*pi*f1*t1+phi);
elseif x == sawtooth
    g = (-(2*A)/pi)*(atan(cot((pi)/(1/f1)*t)))
end

Some questions in random order :-

1) What language is this ? Certainly not C.
2) Are you getting any error messages at all ?
3) Why do you have a semicolon at the end of line 12 ? Do you know what the effect of that is ?
4) What is the meaning of this line t1=-2*pi:pi/SampleRate:2*pi; ?
5) Are you sure a statement like if x == sin works ? Should that not be if x == 'sin' ?
6) Is the value of variable pi defined anywhere ?
7) What are those first 3 statements supposed to do ?

EDIT - Now I see from your other post this is matlab code. Should not have been posted in the C forum.

Hi.

Is this matlab code?

Im not sure, what you are up with the code, i suggest you to comment your code much more better.

For some reason, i cant now use code tags, so lets do without.

Should this: g = (-(2*A)/pi)*(atan(cot((pi)/(1/f1)*t)))
be like this: g = (-(2*A)/pi)*(atan(cot((pi)/(1/f1)*t1)))
