% Write a length conversion chart to a file

% Call a function to get the max length in feet

maxl = promptMaxL;

% Call a function to write the chart to a file

lengthChart(maxl)

promptMaxL.m

function maxl = promptMaxL

% This function prompts the user for a max length in feet

% It error-checks to make sure it is a positive integer

% Format of call: promptmaxl or promptmaxl()

% Returns the integer maximum length in feet

inputnum = input('Enter the maximum length: ');

num2 = int32(inputnum);

while num2 ~= inputnum | num2 < 0

function lengthChart(maxl)

% Creates a chart of converting feet to

% meters and writes it to a file
