Matrix sequence go diagonal

Hi am ,trying to write a function which would display following sequences diagnaly :

1,3,10,33,109,360 [EDITED]

But am not sure how to do that , i have done a little bit,but am now stuck ( am kinda new to matlab and was just trying to learn it for the future ), any help would be great .

Or even if you could show me a refference which i could go of of , would be good too .

"display following sequences" <=== What sequences? You never showed the example. In the meantime, try fprintf();

for k = 1 : 10
	fprintf('%sX\n', repmat(' ', 1, k));
end

sorry about that , how would i make it so it would *3+(the previous term),if you know what i mean .

Sequence:

1,3,10,33,109,360

Please post, what you have tried so far. How many elements do you want to produce?

[Ainars Cernavskis]

@Jan i havent done muchs becasue am stuck ,and regarding elements i would like to produce 15 elements

n = input ('sequence_matrix_')
C = n
B = [1:C]*3
A = diag(B)

The original question may be beneficial for people who wish to learn how to fill a vector sequence with desired values.

This isn't your homework is it? Try this:

% 1,3,10,33,109,360
vec = [1,3,10,33,109,360]
for k = 1 : length(vec)
	fprintf('%d, ', vec(k) + 3);
end
fprintf('\n');

You get:

vec =

1 3 10 33 109 360

4, 6, 13, 36, 112, 363,

Is that what you want? And why do you want this? What's the use case?

@Image Analyst No this isnt homework , am just going to university next year and on of the modules is Matlab/simulink ,and i just wanted to ,try it out . Ive found some questions online which asks you make a funciton ,but it dosent show you the answear so i was wondering i could find the correct answear here or something similar to help me out a little bit . and see how everything works .And thank you

n = 6;              % Or if you want: input ('sequence_matrix_');
v = zeros(1, n+1);  % Pre-allocation
v(2) = 1;           % Initial values: [0, 1]
for k = 2:n
  v(k + 1) = v(k) * 3 + v(k - 1);
end
v(1) = []           % Remove leading zero

v = 1×6

1 3 10 33 109 360
