Inserting rows at a table in MATLAB

Question

I am trying to add rows at the end of table. For example:

LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];
Tab=table;
s=struct;
for i=1:5
    s.name=LastName{i};
    s.age=Age(i);
    s.heigt=Height(i);
    s.weight=Weight(i);
    s.BP=BloodPressure(i);
    temp=struct2table(s);
    Tab(end+1,:)=temp;
end

The table is declared empty, it adds the 1st row, but in the second iteration of the for loop gives below error message:

Subscripted assignment dimension mismatch for table variable 'name'.

I understand that this happens because of the variable name has more characters in the second iteration. Is there any way to implement this?

This is a sample code I generated to explain my problem. In my actual code, the problem is similar, but a structure type variable is being returned from a different function which I can't modify.

Answer 1

First define the whole structure array:

LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];
s = struct('name',LastName,'age',num2cell(Age),...
    'heigt',num2cell(Height),...
    'weight',num2cell(Weight),...
    'BP',num2cell(BloodPressure,2));

And then convert it to table:

Tab = struct2table(s);

The result:

Tab = 
       name       age    heigt    weight        BP    
    __________    ___    _____    ______    __________
    'Smith'       38     71       176       124     93
    'Johnson'     43     69       163       109     77
    'Williams'    38     64       131       125     83
    'Jones'       40     67       133       117     75
    'Brown'       49     64       119       122     80
