create a function t=pe^rt. t is total amount, p is the principal loan, r is the loan amount, and t is time in matlab

To create a function t=pe^rt in MATLAB with given input parameters, you can follow the below code:

main.m
function t = calculate_loan(p, r, t)
%This function calculates the total amount with given principal loan, loan amount and time
%   Inputs: 
%           p - principal loan
%           r - loan amount
%           t - time
%   Output:
%           t - total amount

    t = p * exp(r*t); %calculating total amount
end

In the above code, function is used to define a function in MATLAB, p, r, and t are input parameters and t is the output. exp function is used to calculate exponential and the formula pe^rt is used to calculate the total amount.

You can save this function with any filename, for example, calculate_loan.m and run this function from command window or any other script by passing input parameters p, r, t to get the output t.
