arrays - Unable to open a file with uigetfile in Matlab -

-

i building code lets user open files.

reference = warndlg('choose files analysis.'); uiwait(reference); filenames2 = uigetfile('./*.txt','multiselect', 'on'); if ~iscell(filenames2)     filenames2 = {filenames2};    % force cell array of strings end numberoffiles = numel(filenames2);  data = importdata(filenames2{i},delimiterin,headerlinesin);

when run code, prompts show up, press ok, , nothing happens. code stops, telling me :

error using importdata (line 137) unable open file.  error in freqvschampb_no_spec (line 119) data=importdata(filenames2{1},delimiterin,headerlinesin);

i don't have opportunity select file. cellarray stays empty showed in following image.

empty cell array

matlab can't find file have selected. variable filenames2 contains name of file, not full path. if don't provide full path importdata, search whatever file name provide on matlab path, , if can't find it error see.

try - i'm doing single selection ease of description, can similar multiple selection.

[filename, pathname] = uigetfile('*.txt'); fullnamewithpath = fullfile(pathname, filename); importdata(fullnamewithpath)

fullfile useful, inserts correct character between pathname , filename (\ on windows, / on unix).

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
