Hi,

yes it should be possible but its better to create some Anonymous Functions instead of using inline, e.g.

f = cell(10,1);
for i=1:10
    f{i} = @(x) x*i;
end

The output of f looks a bit strange because it seems to be the same function handle all the time, but it isn't:

>> f{1}(1)
ans =
       1
>> f{2}(1)
ans =
       2
>> f{3}(1)
ans =
       3
>> f{3}(4)
ans =
      12

Or:

f = cell(2,1);
for i=1:2
    tmp = inputdlg('enter function handle')
    f{i} = eval(tmp{:})
end

And enter things like:

   @(x)x^2
   @(x)x-3

Make the call to eval fail proof!!

user_input = fprintf('%.1f\n', input('Enter a positive real number\n'));
for i = 1:9 %first input outside the loop;so 9 more inputs
    if user_input >= 0
        user_input = fprintf('%.1f\n', input('Enter a positive real number\n'));
    end
end

MATLAB: Inputdlg requesting input to provide an output of 6 integers as a row vector

Do NOT use str2num! Using sscanf is faster than str2num (and avoids the internal eval call that str2num hides inside):

>> c = inputdlg('Enter six space-separated integers:')
>> v = sscanf(c{1},'%d',[1,Inf])
v =
   1   2   3   4   5   6

To ensure that there are six integers either add an assert:

assert(numel(v)==6,'Input exactly six integers.')

or a while loop:

v = [];
while numel(v)~=6
    c = inputdlg('Enter six space-separated integers:');
    v = sscanf(c{1},'%d',[1,Inf])
end
