how to solv this issue?

LastName = {'Sanchez';'Johnson';'Li';'Diaz'};
Age = [38;43;38;40];
Smoker = logical([1;0;1;0]);
Height = [71;69;64;67];
Weight = [176;163;131;119];
BloodPressure = [93; 77; 83;80];
BP=[125;135;146;150]
T = table(LastName,Age,Smoker,Height,Weight,BloodPressure,BP)
T1=table2cell(T)
T2=T1(:,2:5)

for i=1:4
        for j=1:4
        properties=T2(i,j);
    end
    temp1=T2(i,1);
    temp2=T2(i,2);
    temp3=T2(i,3);
    temp4=T2(i,4);
    temp5=T2(i,5);

    create(temp1,temp2,temp3,temp4,temp5)
end

function create(temp1,temp2,temp3,temp4,temp5)          % now i explained in detail my code
disp('age is')
disp(temp1)
if height==0
      disp(temp4)
elseif height==1
    disp(temp5)
end
end
% % error index in posiotion exceeds array bounds index must not exceeds 4






% R = [25;50;100;250]        This is part of my program which i have tried
% to  explain in simple way
% L=10
% A=5
% for i=1:4
%     res=R(i)
%     resistivity(R,A,L)
% end
% 
% function resistivity(R,A,L)
% Rho=(R*L)/A
% end

i am getting an error index exceeds array bounds

how to rectify this error?

Where is your error. Code executes without error for me.

now plz tell me how to rectify his error?

The error happens on this line:

temp5=T2(i,5);

and is caused by attempting to access an element in column 5 of T2 but T2 has only 4 columns

LastName = {'Sanchez';'Johnson';'Li';'Diaz'};
Age = [38;43;38;40];
Smoker = logical([1;0;1;0]);
Height = [71;69;64;67];
Weight = [176;163;131;119];
BloodPressure = [93; 77; 83;80];
BP=[125;135;146;150];
T = table(LastName,Age,Smoker,Height,Weight,BloodPressure,BP)

T = 4×7 table
     LastName      Age    Smoker    Height    Weight    BloodPressure    BP 
    ___________    ___    ______    ______    ______    _____________    ___

    {'Sanchez'}    38     true        71       176           93          125
    {'Johnson'}    43     false       69       163           77          135
    {'Li'     }    38     true        64       131           83          146
    {'Diaz'   }    40     false       67       119           80          150

T1=table2cell(T)

T1 = 4×7 cell array
    {'Sanchez'}    {[38]}    {[1]}    {[71]}    {[176]}    {[93]}    {[125]}
    {'Johnson'}    {[43]}    {[0]}    {[69]}    {[163]}    {[77]}    {[135]}
    {'Li'     }    {[38]}    {[1]}    {[64]}    {[131]}    {[83]}    {[146]}
    {'Diaz'   }    {[40]}    {[0]}    {[67]}    {[119]}    {[80]}    {[150]}

T2=T1(:,2:5) % columns 2 through 5 of T1 means that T2 has 4 columns

T2 = 4×4 cell array
    {[38]}    {[1]}    {[71]}    {[176]}
    {[43]}    {[0]}    {[69]}    {[163]}
    {[38]}    {[1]}    {[64]}    {[131]}
    {[40]}    {[0]}    {[67]}    {[119]}

for i=1:4
    temp1=T2(i,1);
    temp2=T2(i,2);
    temp3=T2(i,3);
    temp4=T2(i,4);
    temp5=T2(i,5); % error here: T2 has only 4 columns

    create(temp1,temp2,temp3,temp4,temp5)
end

Index in position 2 exceeds array bounds. Index must not exceed 4.

function create(temp1,temp2,temp3,temp4,temp5)
disp('age is')
disp(temp1)
if height==0
      disp(temp4)
elseif height==1
    disp(temp5)
end
end

I don't know the correct way to rectify this error since I don't know what the code is supposed to do, but perhaps T2 should be defined differently. Maybe this:

T2=T1(:,2:6) % 5 columns

or maybe this:

T2=T1(:,2:end) % all columns from T1 except the first one
