MATLAB: Plus or minus calculation

minusplusplus/minus

Hi everyone,

I am trying to take a value, and subtract a vector from it. I want to then take that answer to check if it is within plus or minus a value of 0.025. Is there a function built into matlab for this? If not, will anybody be able to help me put something together?

Maybe something like this is what you need:

if( all(abs(your_value - your_vector) <= 0.25) )
    % etc
end

This might do what you want:

inp = {...
'pass','OK','Out','OK','OK','Out';...
'pass','OK','Out','OK','OK','Out';...
'fail','OK','Out','Out','OK','Out';...
'pass','OK','Out','OK','OK','Out';...
'pass','OK','Out','OK','OK','Out';...
'fail','OK','Out','Out','Out','Out';...
}; % from your comment above
out = inp;
idx = strcmp(out(:,1),'fail');
out(idx,2:end) = strrep(out(idx,2:end),'Out','OutSpec')

output:

out = 
  'pass'    'OK'    'Out'        'OK'         'OK'         'Out'    
  'pass'    'OK'    'Out'        'OK'         'OK'         'Out'    
  'fail'    'OK'    'OutSpec'    'OutSpec'    'OK'         'OutSpec'
  'pass'    'OK'    'Out'        'OK'         'OK'         'Out'    
  'pass'    'OK'    'Out'        'OK'         'OK'         'Out'    
  'fail'    'OK'    'OutSpec'    'OutSpec'    'OutSpec'    'OutSpec'

MATLAB: Plus-minus function

Hi Sean,

You can do something like

Y=B/2*(1-(4*X.^2)/L^2)*(1-Z.^2/D^2);
Y = [Y -Y];
