Create a new variable

Hi,

This is a beginners question!! I want to create a new variable: CUENEUTRALONSET that will have the same values than CUEONSETTIME whenever the conditions block and type are '1'

I have tried the following with no success at all:

if all (['Block' == 1, 'Type' == 1])
    then CUENEUTRALONSET = CUEONSETTIME(:,1);
end

I have (80*1) double variables in my workplace imported as column vectors from excel: Block, CUEDURATION, CUEONSETTIME, IMAGEONSETTIME, Type

Any suggestion will be highly appreciated.

Thanks so much!!

MATLAB does not use "then"

Thanks so much for answering! I have tried it without then and still no success.... V

all (['Block' == 1, 'Type' == 1]) is always false (=0)

Thanks for the comment, but I am really a beginner, what do you mean by it's always false? How should I indicate matlab the conditions in order to get the values that i want for the new variable? Thanks so much!

[Azzi Abdelmalek]

if Block==1 & Type==1
   CUENEUTRALONSET = CUEONSETTIME(:,1);
end

[Victoria]

still not working... any ideas? Thanks so much!

What are values assigned to Block and Type variables? Can you give more informations about your code

[Victoria]

So finally I'llmanaged (with help) and the code that works is:

count=0;
CUENEUTRALONSET = zeros(80,1);
for i=1:length(Block==1)
  count=count+1;
  if Block(i) == 1 && Type(i) == 1
      CUENEUTRALONSET(count)=CUEONSETTIME(count);
  end
end
