MATLAB: Embedding after every odd letter

odd position

I want to embed data after every odd letter of a word. For example Most is my text and I want to embed 202D. Expected output M202Dos202Dt.

This is quirky enough that I suspect it's homework, though you did not tag it as such. And since we're not supposed to do your homework for you (so you don't get into cheating trouble with your institution/teacher) I suggest you just look at my solution to your other, very similar question here : Click here

Then figure out how to modify only the odd numbered indexes. Hint:

for k = 1 : 2 : length(words) % Loop to do words 1, 3, 5, etc.
    thisWord = words{k}
end

MATLAB: Add bits before last alphabet of every word

Try this:

str = 'MATLAB is a super awesome program';
words = strsplit(str)
for k = 1 : length(words)
	thisString = words{k};
	if length(thisString) >= 2
		words{k} = sprintf('%s%c%c', thisString(1:end-1), char(hex2dec('2020D')), thisString(end));
	end
end
% Reconstruct into a single string
words
str2 = [];
for k = 1 : length(words)
	thisString = words{k};
	str2 = sprintf('%s %s', str2, thisString);
end
str2

You'll see in the command window:

words =

1×6 cell array

{'MATLAB'} {'is'} {'a'} {'super'} {'awesome'} {'program'}

words =

1×6 cell array

{'MATLAB'} {'is'} {'a'} {'super'} {'awesome'} {'program'}

str2 =

' MATLAB is a super awesome program'

except that the FFFF in the boxes don't show up in MATLAB - they're just little empty boxes.

MATLAB: Find the alphabetic word product

See the code below for some more guided hints in an almost finished form. You don't need to call the input function btw. You can call the function by using e.g.

word_product('hello')

If you see a function you don't know, read its documentation. For most common tasks there exists a Matlab function. As an example: the sum function will calculate the sum of an array. Generally a combination of Google, the documentation, and guesses will get you there.

function p=word_product(s)
%convert a word to a ceasar cypher product
%(i.e. convert letters to numbers (a=A=1, b=B=2, etc), and calculate the
%product of these numbers)
%convert all letters to lowercase so we don't need to worry about uppercase
s=SomeFunction(s);
%Now convert the letters to numbers
%This can be done with a tedious lookup for all 26 cases, but this is
%Matlab, there is probably an easier way; and luckily there is.
s=double(s);
%This is not yet correct (nor technically even needed for the next step),
%so you will have to do an extra edit.
%Check out what double() does to char arrays (run in command window):
%double('a')
%double('ab')
%Now we can calculate the product:
p=SomeOtherFunction(s);
end
