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.

Ran in:
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
