This example shows how to create a simple mortgage amortization calculator app. It includes the following components to collect user input, calculate monthly payments, and plot the principal and interest amounts over time:
Numeric edit fields — allow users to enter values for the loan amount, interest rate, and loan period. MATLAB® automatically checks to make sure the values are numeric and within the range specified by the app. A fourth numeric edit field displays the resulting monthly payment amount based on the inputs.
Push button — executes a callback function to calculate the monthly payment value.
Axes — used to plot the principal and interest amounts versus mortgage installment.
