How do I multiply an integer with a single value from the matrix?

%Start of the code
Module_Information = inputdlg ({'Thrust','Mixture Ratio','Reserve'},'Test', [1 50; 1 50; 1 50;]);
Exhaust_Veloctiy = 4 * Module_Information(1,1)
%End of the code

How do I extract "Moduel_Information(1,1)" or the "Thrust" and multiple with a integator, such as 4.

Is it MATLAB? MATLAB doesn’t use // for comment.

[Suleman Jalal]

Yes. It should have been a "%", instead of "//".

You need to convert the character vector (contained in the output) into numeric, e.g.:

C = inputdlg(...); % C is a cell array of character vectors!
N = str2double(C{1}) % N is numeric!
N*4

Thank you so much, the "str2double" was what I was looking. It worked.

Answer 2

Here Module_Information is cell

>> whos Module_Information
  Name                    Size            Bytes  Class    Attributes

  Module_Information      3x1               192  cell      

So

Exhaust_Veloctiy =4*Module_Information{1,1}

I am not sure, however the answer does not correlates with the correct output. I attached a screenshot below of my code in the comman window.
