i am trying to run this code but is not working can you please help me with this
%%
%Data Collection and Labeling
clc;
clear all;
labelPoints = {[2,50],[51,80]};
NoOfFailureModes = 2;
estimateRULFlags = [false, true];
path = 'Datasets/';
labels = {[categorical("OFF"),categorical("ON"),categorical("DUCT BLOCKAGE")],[categorical("OFF"),categorical("ON"),categorical("ROTOR IMBALANCE")]};
rawdata = cell(NoOfFailureModes);
data = cell(NoOfFailureModes);
for i = 1:NoOfFailureModes
rawdata{i} = readtable([path 'Dataset' num2str(i) '.csv'],'Delimiter',','); %Read the downloaded csv file
data{i} = dataParsing(rawdata{i},labelPoints{i},labels{i},i); %Parse the rawdata
end
function data = dataParsing(rawdata,labelPoints,labels,dataset)
bias = 44;
noOfDataPoints = length(rawdata.entry_id);
labelPoints = [0 labelPoints noOfDataPoints];
for i = 1:length(labelPoints)-1
Label(labelPoints(i)+1:labelPoints(i+1),:) = labels(i); %Create Labels for the data points
end
j = 1;
if(dataset == 2)
offset = 0;
else
offset = 2000;
end
for i = 1:noOfDataPoints
text1 = strsplit(rawdata.field1{i},',');
text2 = strsplit(rawdata.field2{i},',');
text3 = strsplit(rawdata.field3{i},',');
text4 = strsplit(rawdata.field4{i},',');
text5 = strsplit(rawdata.field5{i},',');
text6 = strsplit(rawdata.field6{i},',');
var = zeros(length(text1)-1,6);
flag = true;
for k = 1:length(text1)-1 %to neglect the last comma, use -1
var(k,1) = str2num(text1{k})-bias;
var(k,2) = str2num(text2{k})-bias;
var(k,3) = str2num(text3{k})-bias;
if(var(k,1) ~= -bias || var(k,2) ~= -bias || var(k,3) ~= -bias ) %Turning the device off and on will reset the first data set to all zeroes

Provide the full error message, tell us what line is causing that error (the line number is included in the error message but we don't see line numbers so just tell us the line), and describe what variables are used in that line (class & size).

The error appears to be line 36
text1 = strsplit(rawdata.field1{i},',');
The current error is because the variable field1 contains numeric info. Brace indexing - {i} - is not valid for a vector of doubles. Use parentheses instead.
This will lead to your next error. The function strsplit is for text data. You will get another error:
First input must be either a character vector or a string scalar.
