How do I create this function in Matlab? All of the tutorials seem to use very simple syntax in the functions.
f(t) = {

Perhaps post an image of the formula.

If you have Symbolic Toolbox and R2016b or later, you can use piecewise
Otherwise, you need something like
function ft = f(t)
ft = nan(size(t));
mask = t >= 0 & t < 2;
ft(mask) = t(mask) - 1;
mask = t >= 2 & t < 4;
ft(mask) = 3 - t(mask);
Notice the nan: your function definition does not define any value for t outside of [0, 4) so no number can be assigned for those cases.
