MATLAB: Create n arrays given a specified n with similar names

for loopmatrix array

% split into dfferent event arrays

no_events = length(event_id);
for i = 1:no_events; % no_events can be anything from 1 to 100, and I don't want to write 100 if/elseif statements
  if i == 1
      Event1 = [];
  elseif i == 2
      Event2 = [];
  elseif i == 3
      Event3 = [];
  else
  end
end

How can I write this more concisely?

Best Answer

no_events=10
for i = 1:no_events;
  v.(sprintf('event%d',i))=[]
end

When you are working in MATLAB, get used to the idea that you can reshape a matrix to perform some operation.

MATLAB: N(x)

CODE1)

a=[0 1];                % you tell MATLAB a is a vector
for r=3:100             % the for loop you understand, right?
    a(r)=(r-1)+(r-2);   % you're attributing to the rth term of your vector a values of (r - 1) + (r - 2)
                        % the 1st iteration will be a(3) = (3 - 1) + (3 - 2); a(4) = (4 - 1) + (4 - 2); so on...
end

disp(a)

CODE2)

a=[0 1];                %from this line, a(1) = 0 and a(2) = 1.
for r=3:100 
    a(r)=a(r-1)+a(r-2); % the difference between this and code 1) is that you're performing
                        % the summation calling the indexes in the vector a, rather than r values.
                        % so a(3) = a(2) + a(1) = 0 + 1 = 1
                        % In code 1, a(3) = 2 + 1 = 3
end
disp(a)

Code 3) is the same as 2) Walter mentioned.

Hope that helps...

Cheers
