MATLAB: How to produce all the odd numbers of the form 3x + 1 for any integer x in the interval [100, 1000].

odd numbers mat lab integer interval 100 1000

Question for my university coursework, got no idea where to begin

Best Answer

x=3*(100:1000)+1;
x=x(mod(x,2)==1)

MATLAB: Integers can only be combined with integers of the same class, or scalar doubles

ok apparently this code works but doesnt make any sense to me. Thanks for the help

% Declare row vector of length 6 with random values upto 20
A = round(A)
% Declare columnvector of length 10 with random values upto 50
B = round(B)
%concatnate A and B into new row vector
ABrow=horzcat(A,B')
%concatnate A and B into new column vector
BAcol=(fliplr(ABrow))'
%concatnate 3 elements of A and last 5 elements of B into new row vector
FirstHalfA_LastHalfB =[A(1:3),B(6:10)']

MATLAB: Using sign(x) with -0.00

Matlab does not have a -0.0, therefore what you are seeing must be a -0.000000000000001 or similar, which is hidden by the display format. To see more digits type this in the command window:

format long g

If you have good reasons to claim, that these data are pure noise, you can smooth it:

x(abs(x) < 1e-10) = 0.0;

But be sure to note the physical motivation of the threshold value.
