I really need help on conditonal statements. Can someone help me get started on this question please. Would really appreciate it, I'm new to matlab, and trying to really understand it.

I finished the first two, I just need help on question 3. Im struggling to get started, and also do i need an if statement for each temperature and pressure scenario?

Hint:

To print to command line:

fprintf('The temperature = %f\nThe pressure = %f\n', temperature, pressure);

To set a category, I'd set a category as a number for each:

if temperature > 355
   tempCat = 5;
elseif tempreature > 345 && temperature <= 355
   tempCat = 4;

and so on. Do the same for the pressure. Then to set the overall category as the max of the pressure and temp category, do this:

overallCategory = max([tempCat, pressureCat]);

Then have an if/else where you check the overall category

if overallCategory  == 5
    fprintf('Very Severe\n');
elseif overallCategory == 4
    fprintf(

and so on. Here's a snippet of code to ask for two numbers that is more user friendly than input():

% Ask user for two floating point numbers.
defaultValue = {'45.67', '78.91'};
titleBar = 'Enter a value';
userPrompt = {'Enter temperature : ', 'Enter pressure '};
caUserInput = inputdlg(userPrompt, titleBar, 1, defaultValue);
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Convert to floating point from string.
temperature = str2double(caUserInput{1})
pressure= str2double(caUserInput{2})
% Check for a valid number.
if isnan(usersValue1)
    % They didn't enter a number.  
    % They clicked Cancel, or entered a character, symbols, or something else not allowed.
  % Convert the default from a string and stick that into usersValue1.
    temperature = str2double(defaultValue{1});
    message = sprintf('I said it had to be a number.\nI will use %.2f and continue.', usersValue1);
    uiwait(warndlg(message));
end

and so on.
