MATLAB: Does MATLAB give an error on an axes plot when I change with new variable (a22) in the formula?

values must be increasing and non-nan

Error using set Bad property value found. Object Name : axes Property Name : 'YLim' Values must be increasing and non-NaN.

Error in axis>LocSetLimits (line 208) set(ax,…

Error in axis (line 94) LocSetLimits(ax(j),cur_arg);

end
Error in fourbar (line 395)
axis([qstart qstop min(a22) max(a22)]);

Hi Sven (nice name, btw)

Replace the one line:

axis([qstart qstop min(a22) max(a22)]);

With the two lines:

disp([qstart qstop min(a22) max(a22)])
axis([qstart qstop min(a22) max(a22)]);

And then re-run your code. I bet that the last thing before it errors will tell you is that your max(a22) is equal to min(a22).

After that you can probably replace it with:

padding = 0.5; % Just some number that gives you a reasonable axis size
axis([qstart qstop [min(a22) max(a22)] + [-1 1]*padding]);

Thanks, Sven.

MATLAB: Does Matlab give an error for axes

It's not a warning for the axes, it's a warning for the line and it means exactly what it says! You can't have a line with two xdata and three ydata since they don't line up!

Consider this:

plot(1:10,1:12)

It doesn't work for the same reason.

It is asked for "signed integer". Then uint32 is not an option, because it is unsigned.

x = 'NONE';   % requires quotes

The operator is missing in:

elseif maxA<= ((2^32)-1)   maxA > ((2^16)-1) ;
                        ^^

In addition this does not restrict the minA part.

You do not have to exclude e.g. the int8 range, if it was excluded already:

if maxA<=((2^7)-1) && minA>=-(2^7);
   x = 'int8';
elseif maxA<=((2^15)-1) && maxA>((2^7)-1) && minA>=-(2^15) && minA< -(2^7);
    x='int16';

Easier:

if maxA <= 2^7 - 1 && minA >= -2^7
   x = 'int8';
elseif maxA <= 2^15 - 1 && minA >= -2^15
   x = 'int16';

I'd prefer a loop:

TypeList = {'int8', 'uint8', 'int16', 'uint16', ...
            'int32', 'uint32', 'int64', 'uint64'};
x = 'NONE';
for k = 1:numel(TypeList)
  if isequal(double(A), double(cast(A, TypeList{k})))
    x = TypeList{k};
    break;
  end
end

Or:

minA = min(A(:));
maxA = max(A(:));
x    = 'NONE';
for aType = {'int8', 'int16', 'int32', 'int64'}
  aType = TypeList{k}
  if minA >= intmin(aType) && maxA <= intmax(aType)
     x = aType;
     break;
  end
end

minA = min(A(:));
maxA = max(A(:));
x = 'NONE';
for k = [8,16,32,64]
  if minA >= -2^(k-1) && maxA <= 2^(k-1)
     x = sprintf('int%d', k);
     break;
  end
end
