Using fprintf to printing non-vowels in command window

Trying to adjust a previous program to print in the command window all the non-vowels from a inputted text file how do i fprint the code i have to show in the command window all the individual letters that arent vowles.

If text is "I love golf" command window should display like: lv glf

clear all 
clc

inputfile = fileread('SampleText.txt'); 
Number_of_nonvowels = vowellesscounts(inputfile) % original

function w = vowellesscounts(s)
	w=0;
	l=length(s);
	for i=1:l
		if s(i)=='b' || s(i)=='c' || s(i)=='d' || s(i)=='f' || s(i)=='g' || s(i)=='h' || s(i)=='j' || s(i)=='k' || s(i)=='l' || s(i)=='m' || s(i)=='n' || s(i)=='p' || s(i)=='q' || s(i)=='r' || s(i)=='s'|| s(i)=='t' || s(i)=='v' || s(i)=='w' || s(i)=='x' || s(i)=='y'|| s(i)=='z'
			w=w+1;
		else
			continue
         
		end
	end
end

function v = vowellesscounts(s)
  v = '';
	w=0;
	l=length(s);
	for i=1:l
		if s(i)=='b' || s(i)=='c' || s(i)=='d' || s(i)=='f' || s(i)=='g' || s(i)=='h' || s(i)=='j' || s(i)=='k' || s(i)=='l' || s(i)=='m' || s(i)=='n' || s(i)=='p' || s(i)=='q' || s(i)=='r' || s(i)=='s'|| s(i)=='t' || s(i)=='v' || s(i)=='w' || s(i)=='x' || s(i)=='y'|| s(i)=='z'
			w=w+1;
            v(w) = s(i);
		else
			continue
         
		end
	end
end

Note: your code does not achieve the documented purpose. Characters such as '$' are non-vowels, but they are not taken into account. Also, you are not taking into account upper-case characters.

Hint:

ismember('Now is the timing', 'Nni')

ans = 1×17 logical array
   1   0   0   0   1   0   0   0   0   0   0   0   1   0   1   1   0

Hi @Walter Roberson, thanks for the resposne but i'm relatively new to matlab so not reallly sure what you are hinting at besides the upper case letters.

i still dont understand how to use the fprintf function to display each individual non vowel in the command window

[Walter Roberson]

Hint: displaying only the event numbers in a certain range

A = [2 7 3 8 7 6]

A = 1×6

2 7 3 8 7 6

B = 2:2:10

B = 1×5

2 4 6 8 10

mask = ismember(A,B)

mask = 1×6 logical array
   1   0   0   1   0   1

A(mask)

ans = 1×3

2 8 6

thanks @Walter Roberson, sorry i get what you mean now, replace the matrix values with letters?

can you help me with fprintf at all?

[Walter Roberson]

result = A(mask);
fprintf('Yadda yadda, you wanted to know: %s\n', result)

[Joe Ainsworth]

@Walter Roberson i still cant get the fprintf working to display it how i explained in the question

[Walter Roberson]

inputfile = 'I love golf';
Number_of_nonvowels = vowellesscounts(inputfile); % original
fprintf('Edit this to say whatever you want: %s\n', Number_of_nonvowels);

Edit this to say whatever you want: lvglf

function v = vowellesscounts(s)
  v = '';
	w=0;
	l=length(s);
	for i=1:l
		if s(i)=='b' || s(i)=='c' || s(i)=='d' || s(i)=='f' || s(i)=='g' || s(i)=='h' || s(i)=='j' || s(i)=='k' || s(i)=='l' || s(i)=='m' || s(i)=='n' || s(i)=='p' || s(i)=='q' || s(i)=='r' || s(i)=='s'|| s(i)=='t' || s(i)=='v' || s(i)=='w' || s(i)=='x' || s(i)=='y'|| s(i)=='z'
			w=w+1;
            v(w) = s(i);
		else
			continue
         
		end
	end
end

thanks alot, i was missing the 'number_of_nonvowel'

very much appreciated @Walter Roberson
