MATLAB has no implicit multiplication: you must use explicit multiplication, typically the .* operator
MATLAB uses exp(value) for e^value

It's quite easy to do, define an array for 't' and then write your equation by keeping in mind the multiplication rule described by Walter Roberson and simply use plot command

Hi,
For plotting the graph of some function/equation you are required to give an interval on which the function value is displayed. You may use fplot for plotting graph of a function.
Following command might help.
fplot(@(t) 5*exp(-t/300),[0,10],'MeshDensity',500);
Here the first part is the function you want to plot, second is for the range you plot it for and ‘MeshDensity’ represents the number of points for which the function is evaluated. As per the documentation, for a ‘MeshDensity’ of 500 total number of evaluations are 999.
