MATLAB: Help with restricting input

inputMATLABrestriction

I am working on a script that asks for an input to be given between 1 and 100. I would like to have the restriction that the input is limited to between 1 and 100, and that the number must be a whole number.Here is the code:

number=input('Enter a whole number between 1 and 100:')

while number<1 || number>100

display('Not a valid number please try again')

number=input('Enter a whole number between 1 and 100:')

end

I can't figure out how to get it to set a restriction to non-whole number values. Please let me know how to specify this. I have been searching for a while and haven't found the solution.

Suprisingly, just run your specification and it works in MATLAB

number=input('Enter a whole number between 1 and 100:')
while number<1 || number>100 
    display('Not a valid number please try again')
    number=input('Enter a whole number between 1 and 100:')
end

myCell = {}; k = 0;
for i = 1:5:number

end
writecell(myCell,fullfile(myFolder,'myFile.xls'))

p.s: this is not an "optimal" solution.

MATLAB: Finding all numbers which is divisible by 5

Hi,

In your mod command you want to compare the number variable to 5, not a (a doesn't change). This is why you're getting unexpected results. I would use zeroes to initialize z so that you can save each number that is divisible by 5 like:


a=input('Enter the threshold: ');
number = 1; z = zeros(1,a);
while number <= a
    if mod(number,5) == 0
         z(number) = number;
    end
    number=number+1;
end

And then use

find

to extract the indices of z that are nonzero and print them out.

I hope this helped
