What coding do i use in MATLAB to obtain the symbolic fourier transforms for X(t)=exp(-t^2).
I new to MATLAB and i have no idea how to do this.

syms makes symbolic variables, not the standard numerical double preceision data.
% example:
x1=3
syms x2
y1=2*x1
y2=2*x2
%end
returns y1 equals the constant 2 and y2 is the symbolic expression 2*x.
The symbolic functions that should affect you include:
fourier
ifourier
laplace
ilaplace
there are also "overloaded" functions. A normal function like "diff" returns the difference between adjacent elements in a vector. Its a poor-man's gradient. if you apply the diff function to a symbolic expression, it becomes a symbolic differentiation. int applied to symbolics becomes a symbolic integration.
help sym/diff
help sym/int
I hope that helps.

syms t
fourier(exp(-t^2)
should return a the transfrom. probably a heavyside function.
you could always use the command
