MATLAB Creating Graphical User Interfaces

App that Calculates and Plots Data Based on Numerical

Input

This app shows how to use numeric edit fields to create a simple mortgage amortization

calculator. 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.
