MATLAB: How to save different files in for loop

Hi,

I'm trying to create separate folders each with a .mat file with temperature data in them (from Feb01 to Apr30). The folders should be like so:

ex) Feb01 folder > Feb01.mat (this .mat file should have 24 temperature data values in them)

But when I run my code I get an error message that says:

Error using save
Must be a text scalar.
Error in Copy_of_testingdates (line 46)
    save(FileName,'DataAdj')

Here is my code:

%calibration data
run('HoboConstants.m')
%read data from Feb01 to Apr30
HoboData_C=readmatrix('AB1_Jan22_to_May3.csv','Range','B234:C2393');
HoboData=HoboData_C(:,2)+273.15;
%set month and date vectors
month={'Feb','Mar','Apr'}; %had to attach them bc k reads one alphabet as one column
max_date=[28 31 30];
FileName1={};
DataAdj=[];
FullHoboAdj=[];
%set constants
k=1;
q=1;
m=1;
%saving separate files as ex)"Feb22"
for i=1:24:2136 %decreased 2160 by 24 so that loop runs 89 times
    %calibrate data
    DataAdj=HoboData(i:(i+23),1)-hoboAB1;
    %gives the full calibrated data from Feb01 to Apr30
    FullHoboAdj=[FullHoboAdj;DataAdj];
    
    if q>max_date(m)
        q=1;
        if m<=length(max_date)
            m=m+1;
        end
        if k<=length(month)
            k=k+1;
        end
    end
%creating FileName
    z=length(FileName1);
    %this will name FileName1 as 'Jan01' up to 'Apr29'
    FileName1{z+1}=sprintf('%s%02d',month{k},q);
    %flipping the horizontal FileName1 to be vertical
    FileName=reshape(FileName1',{},1);
    q=q+1;
    
    save(FileName,'DataAdj') %#####This is where the error is#####
end

Thank you!
