Please anyone helping me with this question can you code using Matlab software, please.

Answer 1

MATLAB Script:

close all
clear
clc

% Example function calls
result1 = findLetter('ayAzAb', 'a');
result2 = findLetter('ayAzAb', 'b');
result3 = findLetter('ayAzAb', 'B');
result4 = findLetter('ayAAb', 'z');

function found = findLetter(text, letter)
found = ~isempty(find(text == letter, 1));
if found
fprintf('Letter %c is present in the string %s\n', letter, text)
else
fprintf('Letter %c is not present in the string %s\n', letter, text)
end
end

Example Outputs:

Letter a is present in the string ayAzAb
Letter b is present in the string ayAzAb
Letter B is not present in the string ayAzAb
Letter z is not present in the string ayAAb
