MATLAB: Right display of error!

errorstring

I have two variables in my .m file, which calculates- "possible_hrs" and "diff". The error is thrown if the required hours > possible hours.

error('For this Regular working shift, the maximum working time for a ONE-GO step is ',possible_hrs,'hours.', ...
            'Please decrease Step Duration weather by' ,diff, ' hours or increase the working hours');

But the MATLAB gives me a warning- "The Format String might not agree with the argument count".

And finally it is not displayed correctly also (in the situation of error). What could be the solution?

Hi,

After I read the Matlab help I think this should work:

error('For this Regular working shift, the maximum working time for a ONE-GO step is %d hours. Please decrease Step Duration weather by %d hours or increase the working hours', possible_hrs, diff);

Convert to a timeseries() object and use retime()

Or:

Data = rand(365,1);
Data_timestamp = datetime(2021, 1, 1:365).';  %use non-leap year !
month_totals = accumarray(month(Data_timestamp), Data)
month_totals = 12×1

   12.5502
   14.1349
   17.2993
   14.2127
   17.4742
   16.3479

MATLAB: Issue with a while loop

You've got the while operating until BAC<=0.08 by adjusting Hrs but one can take the expression

   BAC=BAC-(Hrs*.0140);

and solve for

0.08=0.13-Hrs*0.014

to find

>> (0.13-0.08)/0.014
ans =
  3.5714
>>

What's wrong with your implementation that iterates where it isn't really needed is you're multiplying the difference/0.01 hr by the total hours every time instead of just the reduction/0.01 hr.

>> BAC=.13;
Hrs=0;
dHr=0.01;
Rt=.0140;
dHrRed=dHr*Rt;
while BAC>.08
  BAC=BAC-dHrRed;
  Hrs=Hrs+.01;
end
Hrs
Hrs =
  3.5800
>>

This isn't quite as accurate as the direct solution but given the inherent nature of the problem the correlation probably isn't accurate to a tenth of an hour, either...
