How to create dialog boxes to select the file and display output ?

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'])

Thanks a lot for the reply.

I am having a problem with the second dialog box. The second dialog box should select a spanning window either '9' or '11' using fname2 as below:

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

fname2=inputdlg(prompt2);

Z2=smooth(data,fname2,'rloess');

I am experiencing the following error:

??? Undefined function or method 'le' for input arguments of type 'cell'.

Error in ==> smooth at 145

if span <= 0

Error in ==> trial8 at 37

Z2=smooth(data,fname2,'rloess');

Please help me.

fname2 is a cell, you must give a string argument

char(fname2)

[Paulo Silva]

str2num(char(fname2))

Thank you.

I have tried char(fname2) as following:

Z2=smooth(data,char(fname2),'rloess');

I am experiencing the following error:

??? Error using ==> smooth at 188

SMOOTH: Unrecognized method.

Error in ==> trial8 at 37

Z2=smooth(data,char(fname2),'rloess');

Please help me out.
