I need help with this MATLAB question

For this, you will write Matlab program that will do the following:

• Use a pop-up dialog to query the user for the name of a text file.
• Read a matrix of numbers from the file into your program. This data will be arranged so that each column corresponds to a "subject", and each row to some experimental "data" about that subject taken over multiple days.
• Print out the raw data to the console.
• Make a plot containing two subplots(one above the other in a single figure window):

-Subplot 1: plot the raw data for each user against time in a single plot.

- Subplot 2: plot the mean and standard deviation over all users against time

- Label the axes on all plots(including the plots below)

• Using for loops, remove all negative data(specifically, set any negative data to zero)
• Print out the altered data to the console
• Make a second plot with the same description as the first using the modified data.
• Confirm with the user using a pop-up dialog before closing all figures.

You must follow the requirements below to make automated grading possible:

• Use the provided Matlab functions get_infilename() and load_if_possible(), and call confirm_dialog() before closing your figures.
• Use disp() to show raw data (where it says "print out the data to the console").
• First plot must be figure(1)
• Second plot must be figure(2).
• Use Matlab's default fonts, colors,linestyles, and all other plot properties.
• Do not use call any other Matlab functions that create dialogs or in any other way prompt the user for input(for example: dialog, pause,listdlg).

OK. What have you done, and where are you stuck?

I am stuck with making subplots.

[Matt J]

See the subplot command

Thank you!!

Also, I know how to get user input but how do i get it through a pop up box?

[Ankit]

hows your confirm_dialog() function looks like?

One option is inputdlg,
