MATLAB: Sequence of adding numbers

answer sequence.for operationsequence

Hi i have like this question. Lets say i have this code : for i=1:4 C=2+i; end

this gives me this answer: C=3, C=4,C=5,C=6

BUT I want like this answer: C1=3, C2=4, C3=5, C4=6, which is with numbers after letter C. Can anyone help please…thanks 🙂

The best way is

for k=1:4
  C(k)=2+k
end

MATLAB: A command like “unique” for matrices

A general solution that does not concatenate the data and works for any size arrays:

% Fake data:
A = [1;2;3];
B = [1;2;3];
C = [4;5;6];
R = {A;B;C}
% Method:
N = numel(R);
X = false(1,N);
for ii=2:N
    Y=false;
    for jj=1:ii-1
        Y = Y || isequal(R{ii},R{jj});
    end
    X(ii) = Y;
end
R(X) = []

MATLAB: How to access element with same index from multiple cells

 >> extract = @(C, k) cellfun(@(c)c(k), C) ;
 >> extract(a, 1)
 ans =
     1     1
     1     1
 >> extract(a, 3)
 ans =
     3     3
     3     3

if you want to make a lightweight function for extracting various elements of various cell arrays, or simply

 >> cellfun(@(c)c(1), a)
 ans =
     1     1
     1     1

if it is just for cell array a and you are fine with hard coding the element # in the expression.
