MATLAB: Error in the function in the for loop

date mathMATLAB

Hello I am trying to make a function. I have for inputs datetime 3 of them one of them is logical. I am trying to calcutate a number from many rows. I have for loop, my max iteration is the height of my table. I have cases for logical data part of my function to decide the final output, I am unable to put the final answer in an order as output. I am getting an error with exceeding matrix dimensions.
function [Count SensoredData] = sensor(StartDate,EndDate,PatientinResearch,LogicalDeath)
% X is start of the research.
% Y end date of the Research.
% E is number of days patient stay in the research
% Z is if death is occured or not.
if ~isdatetime(StartDate)
error('MyComponent:incorrectType',...
'Error. \nInput must be a DateTime for StartDate, not a %s.',class(StartDate))
end
if ~isdatetime(EndDate)
error('MyComponent:incorrectType',...
'Error. \nInput must be a DateTime for EndDate, not a %s.',class(EndDate))
end
if ~isdatetime(PatientinResearch)
error('MyComponent:incorrectType',...
'Error. \nInput must be a DateTime for PatientinResearch, not a %s.',class(PatientinResearch))
end
if ~isa(LogicalDeath,'logical')
error('MyComponent:incorrectType',...
'Error. \nInput must be a Logical for LogicalDeath, not a %s.',class(LogicalDeath))
end
X = StartDate;
Y = EndDate;
E = PatientinResearch;
Z = LogicalDeath;
T = table();
% totalTimeOfResearch = caldays(between(X,Y,'days'));
%
% sdn1 = datenum( Y );
% sdn2 = datenum( E );
% format long
%
[n,m] = size(X);
for i = 1 : 1 : n
if caldays(between(X,Y,'days')) >= caldays(between(X,E,'days'))
switch Z
case 0
p = 0;
T(i,:) = [i p];
case 1
p = 1;
T(i,:) = [i p];
end
end
if caldays(between(X,Y,'days')) < caldays(between(X,E,'days'))
switch Z
case 0
p = 1;
T(i,:) = [i p];
case 1
p = 0;
T(i,:) = [i p];
end
end
end
Count = T(:,1);
SensoredData = T(:,2);
end

  • Try to define the size of T before using it. Also, make sure that the line of code
    [n,m] = size(X);
    is giving you the value of n you expect.
