MATLAB: How to create dialog boxes to select the file and display output

dialog-box

Hello all, I am trying to create a standalone application which opens dialog boxes to select the values and displays output. when I am trying to create dialog boxes using the following code, I am getting errors.

function trial8

prompt1={'Enter input file name (without extension [.mat]): '};

fname1 = inputdlg(prompt1); prompt2=('choose spanning window 9 or 11 (without extension [.mat]):');

fname2=inputdlg(prompt2);

[NUM,TXT,RAW]=xlsread('2.csv')

[row,col] = size(NUM);

I want the dialog box to ask for the file selction and display the corresponding output. Can anyone please help me out. Regards,

You got the line wrong

[NUM,TXT,RAW]=xlsread('2.csv')

You ask the user for the name of the file so you should use that input

 [NUM,TXT,RAW]=xlsread([char(fname1) '.csv'])

MATLAB: Need help extracting the input from a dialog box and then fprintf it in the command window.

Try this:

titleBar = 'Enter data';
caUserInput = inputdlg(Prompts, titleBar, 2);
if isempty(caUserInput)
  return
end; % Bail out if they clicked Cancel.
