How to print values stored in a cell as strings (whole words) in Matlab?

For

A=[100;300;1000;240]

and

B=cell(8,1)

I have the following results stored in a B

[100]
[300]
[1000]
[240]
[100;300;240]
[100;1000]
[300;1000]
[100;300;1000]

I want to print these to display the output as :

choose first
choose second
choose third
choose fourth
choose first or second or fourth
choose first or third
.
.
etc

Basically, from the array A=[100;300;1000;240] , I want each value inside of it to be represented by a string, and not one variable. Any idea how to do this ?

note :

For my code, I want the user to input their own numbers in array A, and hence the length of A is variable and can be more than 4. The size of cell B also changes according to a formula, so it is not always fixed at size 8.

I would also appreciate a simple code, nothing too complex (unless necessary) as I don't have professional knowledge with matlab. A simpler code can help me understand and learn.

for mapping I would just use a map object

index_to_string = containers.Map(keySet,valueSet)

where

keySet = 1:20
valueSet = {'first'; 'second'; ...; 'twentieth'}

If A is available before printing, you can use the same valueSet, just cut it down to the size of A.

index_to_string = containers.Map(A,valueSet(1:length(A)))

Example:

G = cell(size(B))
for i = 1:length(B)
    out1 = 'choose ';
    if len(B{i}) == 1
        out1 = [out1, index_to_string(B{i})];
    else
        temp = B{i}
        for j=1:(length(temp)-1)
            out1 = [out1, index_to_string(temp(j)), ' or ' ];
        end
        out1 = [out1, index_to_string(temp(end))];
    end
    G{i} = out1
end

This answer is entirely based on JaredS's answer. I have just clarified your doubts.

Write this in some m-file.

Choices=A; Results=B;
%simple boolean to indicate whether a choice has been made already
answerChosen = 0;

for k = 1:length(Results)
    Response = 'choose';
    for m =  1:length(Choices)
        if any(Results{k} == Choices(m))
            if answerChosen
                Response = [Response ' or ' NumToOrd(m)];
            else
                answerChosen = 1;
                Response = [Response ' ' NumToOrd(m)];
            end
        end
    end
    fprintf('%s\n',Response);
    answerChosen = 0;
 end

Please write the following function in a separate file and put that in the same directory as the previous m-file. Then you should get an error saying: "Undefined function 'NumToOrd' for input arguments of type 'double'."

function ordinal = NumToOrd(number)
switch number
    case 1, ordinal = 'first';
    case 2, ordinal = 'second';
    case 3, ordinal = 'third';
    case 4, ordinal = 'fourth';
    otherwise, ordinal = 'out of index';
end

Here's how I'd do it

function IChooseYouPikachu(Choices, Results)
% put in A for choices and B for results

%simple boolean to indicate whether a choice has been made already
answerChosen = 0;

for k = 1:length(Results)
    Response = 'choose';
    for m =  1:length(Choices)
        if any(Results{k} == Choices(m))
            if answerChosen
                Response = [Response ' or ' NumToOrd(m)];
            else
                answerChosen = 1;
                Response = [Response ' ' NumToOrd(m)];
            end
        end
    end
    fprintf('%s\n',Response);
    answerChosen = 0;
end

function ordinal = NumToOrd(number)
switch number
    case 1, ordinal = 'first';
    case 2, ordinal = 'second';
    case 3, ordinal = 'third';
    case 4, ordinal = 'fourth';
    otherwise, ordinal = 'out of index';
end
