Prompt the user to enter a value for height in inches (59-78) and weight in pounds (90-350). I don't know what I can't do that. I enter the height is 50, but it doesn't require me input again. it just show enter the weight.
inches = input('Enter the height in inches (59-78): ');
while (inches <59 && inches>78)
disp('Enter the height in inches (59-78): ');
end
pounds = input('Enter the weight in pounds (90-350): ');
while (pounds <90 && pounds > 350)
pounds = input('Enter the weight in pounds (90-350): ');
end

You are yusing && operators indicating that x has to be less than 59 and greater than 78. This isn't possible!
You probably mean to have a ||, the or operator.

Use strcmp
doc strcmp
Yopu may also need the ~ operator or not
doc not
E.g:
~strcmp('Sean','F')

If the gender is 'F' then it is not 'M' so the "gender ~= 'M'" part would be true. No matter what you enter, one of the tests is going to be true, and you have used "or" between the parts. Perhaps you should not have used "or".
You should also have used strcmp() like Sean wrote.
