I am importing a mass of files and am processing them, however a short way in there is a blank file so it imports but then the calculations cannot be performed on it and the loop stops.
How do I define if the file is blank either delete or ignore the file then carry on to import the rest of the data?
Below is my script:
%% Import data
numfiles = 10; % number of excel files mydata=cell(numfiles,1); % defining size of mydata
for i=1:length(mydata) % loop to import mutliple excel files
myfilename = sprintf('Trial%i.csv', i); % define file name
mydata{i} = xlsread(myfilename); % import files into mydata
%% Perfrom Calculations
%%Define variables
a= 9.81; % acceleration
fps = 250; % frames per second
%%Calculate Jump Height
no_of_zeros = size(mydata{i,1},1) - nnz(mydata{i,1}(:,5)); %number of zeros
no_of_frames = (no_of_zeros/4); % number of frames
time = ((no_of_frames/fps)/2); % time up
jumph(i,1)=((a*(time*time))/2); % jump height
%%Calculate peak power
loc = find(mydata{i,1}(:,5)==0); loc = loc(1); % returns all the occurences of zero from column 5, then extracts the first
peakp(i,1) = nanmin (mydata {i,1}(1:loc,5)); % finding peak power from E1 to index cell
%%Calculate average power
avp(i,1) = nanmean (mydata {i,1}(1:loc,5)); % finding average power in column 5
%%Plot Results
figure(1); subplot (1,3,1); plot (avp); %subplot (1,3,2);
%plot (b,c);
%subplot (1,3,3);
%plot (a,c);

This is the error:
Error using xlsread (line 247) File C:\Users\Caz\Documents\MATLAB\coursework\Trial6.CSV not in Microsoft Excel Format.
Error in MatlabCoursework (line 15) mydata{i} = xlsread(myfilename); % import files into mydata
On opening the Trial6 document outside Matlab it is blank.
