MATLAB: How to create a 1,12,123,1234 pattern in a triangle

looppattern

How do I make a pattern from 1:N, Lets say N = 5, so it turns out like this:

123

1234

12345

Use a loop or

n = 5;
c = arrayfun(@(nn) 1:nn, (1:n)', 'UniformOutput', false);
celldisp(c)

You obviously can't store the result in a matrix since matrices are square by definition.

Here is the complete answer to all parts of the assignment:

clearvars; clc
%% Part 1.
k=1;
for ii = 1 : 5
    for jj = 1 : ii
        if k >10
            k=k-10;
            fprintf(num2str(k));
        else
        fprintf(num2str(k)) ;
        end
        k = k+1;
    end
    fprintf('\n') ;
end
%% Part 2
k = 65 ;
for ii = 1 : 5
    for jj = 1 : ii
        fprintf(char(k)) ;  
        k = k + 1 ;
    end
    fprintf('\n') ;
end
%% Part 3. Numbers
k=5;
for ii = 1 : 5
    for jj = 1 : ii
        if k >10
            k=k-10;
            fprintf(num2str(k));
        else
        fprintf(num2str(k)) ;
        end
        k = k+1;
    end
    fprintf('\n') ;
end
%% Part 3. Letters
k = 68 ;
for ii = 1 : 5
    for jj = 1 : ii
         fprintf(char(k) ) ;  
       k = k + 1 ;
    end
    fprintf('\n') ;
end

MATLAB: Help.. how would i get 7* to 1*

You can run the for-loop in reverse order too

N = 7; 
for mm = N:-1:1 % equivalent to mm = flip(1:N)
    for nn = 1:mm
        fprintf('*');
    end
    fprintf('\n');
end
