How to create table?

I have 3 Problems named "A", "B", "C". For each three problems, I have 4 Performance Metrics- "D", "E", "F", "G". And for each performance metrics of each problem, I have 11 datas. From these, I want to create a table like this-

How do I do this?

Hi,

One way to have this table is to assign problem name to each of its constituent problem metric.The table can take shape as follows: (I have used random values for stats)

V_table = table( ...
    {'A';'A';'A';'A';'B';'B';'B';'B';'C';'C';'C';'C'}, ...
    {'D';'E';'F';'G';'D';'E';'F';'G';'D';'E';'F';'G'}, ...
    [0.4;0.4;70;60;4;2500;0.01;60;4;2500;0.01;60], ...
    [0.4;0.4;70;60;4;2500;0.01;60;4;2500;0.01;60], ...
    [0.4;0.4;70;60;4;2500;0.01;60;4;2500;0.01;60], ...
    [0.4;0.4;70;60;4;2500;0.01;60;4;2500;0.01;60], ...
    'VariableNames',{'Problem Name','Performance Metrics','Minimum Value','Maximum Value','Mean Value','Standard Value'})

I hope this helps.

problem =["A", "A","A","A","B","B","B","B","C","C","C","C"]';
performance = ["D","E","F","G","D","E","F","G","D","E","F","G"]';
MinVal = randn(12, 1);

T = table(problem, performance, MinVal)

T = 12×3 table
    problem    performance     MinVal
