i have a input problem.Cannot call INPUT from EVALC. in my code

hello this message appear when i try tu publish my program Error using input * Cannot call INPUT from EVALC. Error in hw1 (line 4) year= input('Enter the year (yyyy)\n:'); *

my code is the following:

        year= input('Enter the year (yyyy)\n:');
        month=input('Enter the month: ');
        day=input('Enter the day: ');
        fprintf('\nYou entered %3.0f/%2.0f/%4.0f',month,day,year)
        d=day;
        m=month-2;
        if m<=0
        m=m+12;
        year=year-1;
        endy=mod(year,100); % year's number in the century
        c=(year-y)/100;  % number of centuries
        %formula input
        %weekday= mod((d+((1/5)*(13*m-1))+y+(y/4)+(c/4)-2*c+777),7);
        %week={'Sunday' 'Monday' 'Tuesday' 'Wednesday' 'Thursday' 'Friday'...'Saturday'};
        %fprintf('\n\nYour weekday is: %s\n', week{weekday+1}); % result
        %Subscript indices must either be real positive integers or logicals.
        weekday= mod((d+fix((1/5)*(13*m-1))+y+fix(y/4)+fix(c/4)-2*c+777),7);
        week={'Sunday' 'Monday' 'Tuesday' 'Wednesday' 'Thursday' 'Friday'...
               'Saturday'};
        fprintf('\n\nYour weekday is: %s\n', week{weekday+1}); % result

can anyone help me?

Alejandro - I copied your file and opened it in the MATLAB editor. On the Publish tab, I pressed the Publish button and observed the same error as you. The same error occurs if you run the following in the Command Window

 publish('myScript.m')

This is because the default setting for the publish functionality is to evaluate the code. If you wish to disable this setting, in the editor on the Publish tab, press the down arrow on the Publish button and select Edit Publishing Options. In the Code Settings section change the Evaluate Code from true to false, and press Publish. The resulting HTML (or whatever you have selected as output) should no longer display this error.

If publishing from the command line, just disable the evaluation of your script/program as

 publish('myScript.m','evalCode',false)

[Alejandro Garcia]

thanks a lot, the error message disappear as you mentioned. I was wondering, does the answers of the program should appear or only the code.... for example when you make a program that develop a graphic, the graphic result appear when you publish it. does works the same for this kind code?

[Geoff Hayes]

I guess it is your choice. Given that the default behaviour is to evaluate the code, the intent is probably to run through an example and display the output. Unfortunately, the use of input and evalc doesn't work.

This is just avoiding execution of the code. What if I want to run the same using some temp inputs? Like executing the script with input of year, month etc

[Steven Lord]

Separate the interface and the computation pieces.

• Write a script file that uses input to prompt the user for values for the parameters. This is the interface piece.
• Write a function file that accepts the parameters as input arguments. This is the computational piece.

When you want to perform the computations interactively call the script and have it call the function directly, specifying the values the script received from the user as the inputs to the function.

When you want to perform the computations non-interactively (such as when you want to publish your results) just call the computational function directly and specify the input arguments in that function call.

clc

clear

disp('This program will calculate the time in which the crime was committed')

To=input('Enter the temperature upon arrival.To= '); %temperature in Farenheit

Ts=input('Enter the temperature of the room.Ts= '); %temperature in Farenheit

T=input('Enter the temperature after one hour after the scene.T= '); %temperature in Farenheit

%t= 1 unit in hours

k=-log((T-Ts)./(To-Ts));

NT=input('Enter the normal temperature of the body.NT= '); %temperature in Farenheit

t=-(1/k)*log((T-Ts)./(NT-Ts)); %time in hours fprintf('\nThe time at which the crime was commited was %.2f hours before they arrived\n',t) This program will calculate the time in which the crime was committed

Gave me teh same error. But I do what it says in the instructions and it keep giving me the same error.
