How can I resolve Error Using max function

clear all;
close all;
for kk =1:44
for k=1:50
% here drift values are in the form of drift ratio
eval(['load IDAOutput/EQ_',num2str(kk),'/Scale_',num2str(k),'/StoryDrifts/','Roof.txt']);
Roof_Drift_max(kk,k,:)= max(abs(Roof(:,2)));

MIDR(kk,k,:) =max(Roof_Drift_max(kk,k,:),Story1_Drift_max(kk,k,:),Story2_Drift_max(kk,k,:),Story3_Drift_max(kk,k,:),Story4_Drift_max(kk,k,:),...

I am not certain what you want.
One option is to enclose all the arguments within square brackets [], effectively concatenating them:
MIDR(kk,k,:) =max([Roof_Drift_max(kk,k,:),Story1_Drift_max(kk,k,:),Story2_Drift_max(kk,k,:),Story3_Drift_max(kk,k,:),Story4_Drift_max(kk,k,:),...
This will produce an ‘MIDR’ matrix with the same dimensions as the argument matrices.
Experiment with other approaches to get different results.

I've attached a zip file for your reference

Try this to extract the variables:
uz = unzip('');
k2 = 0;
for k1 = 1:numel(uz)
if ~isdir(uz(k1))
[~,txtname] = fileparts(uz{k1});
k2 = k2+1;
LD{k2,1} = txtname;
LD{k2,2} = load(uz{k1});
I have to unzip it, so I included tahat as part of my code. Change my code to work with the .zip file or it was created from. My code extracts the contents of the .zip file to a series of cell arrays, with the first element of the cell array being the name of the file it came from, and the second cell array the contents of that file as a double matrix.
So to get the information for the first 5 elements of ‘LD(1)’:
BldgPart_1 = [LD{1,1}]
BldgPrtData_1 = [LD{1,2}(1:5,:)]
BldgPart_1 =
BldgPrtData_1 =
0.002 6.9378e-08
0.004 6.9378e-08
0.006 6.9378e-08
0.008 6.9378e-08
0.01 6.9378e-08
and for ‘LD(40)’:
BldgPart_40 = [LD{40,1}]
BldgPrtData_40 = [LD{40,2}(1:5,:)]
BldgPart_40 =
BldgPrtData_40 =
0.002 5.5276e-07
0.004 5.5276e-07
0.006 5.5276e-07
0.008 5.5276e-07
0.01 5.5276e-07
I leave the rest to you.

Yeah, you have to close your arguments with square bracket.
