Where is the logic failure in my code ?

2 次查看(过去 30 天)
Hi All
I have a matrix n x 1 called X , in which I want to move it up or down along vertical axis when I plot it vs time , in a way to make the mean value = 0 if it's not so I created a true false parameter as :
useMean
than can be
True
or
False
and then in the code I do :
if useMean == 'True'
if meanX <0
X= X+abs(meanX);
else
X= X-abs(meanX);
end
elseif useMean == 'False'
X=X;
end
but I noticed the code only can perform when useMean == 'True' , not the 'False' !
this way my rest of the parameters can not be calculated

I got it , I didn't have to write 'True' but simply true, cause true gives logical value 1

Your code can be shortened to
if useMean
X = X - meanX;
end
with no abs() needed.

Use true or false, not 'True' or 'False'. No quotes or capitalization required.
Or don't even use them at all. Your code could be:
if useMean
if meanX <0
X= X+abs(meanX);
else
X= X-abs(meanX);
end
else
X=X; % Even this is not needed.
end
but best would be to use Walter's code in the last comment above.
