1.
Write a function in Matlab that accepts a character string and returns a logical array with true
values corresponding to each vowel and false values everywhere else. Be sure that the function
works properly for both lowercase and uppercase characters.
Solution
%matlab function accepts a string, and returns a logical array in
%which vowels are true and consonants are false.
%Find length of c
function array = stringTological(string)
len = size(string);
array = [];
%Initiate for loop
for i = 1:len
if (string(i) == 'A')
array(i) = 1;
elseif (string(i) == 'E')
array(i) = 1;
elseif (string(i) == 'I')
array(i) = 1;
elseif (string(i) == 'O')
array(i) = 1;
elseif (string(i) == 'U')
array(i) = 1;
elseif (string(i) == 'a')
array(i) = 1;
elseif (string(i) == 'e')
array(i) = 1;
elseif (string(i) == 'i')
array(i) = 1;
elseif (string(i) == 'o')
array(i) = 1;
elseif (string(i) == 'u')

2.
array(i) = 1;
else
array(i) = 0;
end
end
for i = 1:len
disp(array(1));
end
end
%testing
string = 'aalbcd';
stringTological(string);
