matlab table from for loops

Question

0 个投票

for iter = 1:2
  Num_of_Banks = 4
  Initial_Capitals = [ randi([0 100],Num_of_Banks,1) ]
  Total_initial_caps = sum(Initial_Capitals)
end

This will set Num_of_Banks = always 4 and Initial_Capitals = rand

How can I create a table from X num of iterations (Prob = everything that I have tried til now) and store correctly the results?

Trying to make sth like this:

Num_of_Banks  Initial_Capitals
4             amount 1
4             amount 2
4             amount 3
...           ...

(My prog has almost 50 variables to be added so this is a small part of it)

Will appreciate your answers

(R2016a version)

Do you really intend for the #Banks variable to be constant for some N rows or is that also a random or otherwise known number?

Is the initial amount for each one of the random values?

Num_of_Banks is always 4 (or I will change it at eg 100 for the simulations) but it will always be the same from the begining

Vars to rand = Loans / Assets / Risk / RWAs ... (some of them will be computed with for loops eg the RWAs)

I will repeat it 100 (MC simulation) times to regress it after that

Thanks in advance

A table may not be the best for this purpose but iiuc what you're asking for would be something like

Nrows=100;
Num_of_Banks=repelem(4,Nrows,1);
InitialCapital=randi([0 100],Num_of_Banks,Nrows);
Loans=randi([0 20],Num_of_Banks,Nrows);
Assets=randi([100 10000],Num_of_Banks,Nrows);
...
t=table(Num_of_Banks,InitialCapital,Loans,Assets,...);

What the prog does is not fully random (sorry if I didn't say that)

It takes num of banks

For each bank set (=4) sets a rand set of caps and what each bank has to pay to other banks

Uses gras algo (and others) to make the loan matrix

makes some results about digraphs characteristics / ratings / banks default

Puts the result in a matrix row.

For 1 time it creates a table with the results.

(It has many for loops [17 different] / other functions ..)

What I can't connect is how to make this:

run ->give results at 1st time

run again - >give results next time

My first try was auful !!

My 10th try was misserable !!

My after a week (I have read many documents but nothing was common or could not connect them with what I have)

My last try was a function but I don't have a clue where to put the iteration to repeat the process. I have tryed inside the function (set it at 2 repeats -> gives a result that i already know (I have it ) and an 'ans' which is the same (does not look like it had repeat it)).

I used it inside the function (T(? , ?) both cases for ter and :) and it returns the result that I have and errors

I really thank you for your answer and I hope that I will not look aggresive after you read this

Next try that worked??

I put a "for i=1:5" at the beginning

Added at the end a table column for the iter

I had to convert it to array "table2array"

Worked !!!!
