I am generating random numbers (data) with the 3 parameter weibull distribution.

In my code, I have 25 combinations of my parameters (b=1:5; T=1:5) and I want to display every single combination as a histogram.

So at the end, I have 25 histogram of data.

The problem is, only the last combination of my parameter ( b=5, T=5) is displayed.

How can I see ALL 25 histograms with one run?

Edit: I deleted the 2 parameter weibull in my code for better overview about my question.

clear all;

n = 100;

t0 = 0.5;

b = 1:5;

T = 1:5;

for v_T = 1:length(T)

for v_b = 1:length(b)

data(:,v_b,v_T) = wblrnd(v_T,v_b, [n,1]) + t0;

end

end

histogram (data)

ax = gca;

get(ax, 'position')

ax.XLim=[0,10];

Hello Mustafa, you can use subplots inside for loops.

clear all;

n = 100;

t0 = 0.5;

b = 1:5;

T = 1:5;

clf

figure(1)

loopVar = 0;

for v_T = 1:length(T)

for v_b = 1:length(b)

data(:,v_b,v_T) = wblrnd(v_T,v_b, [n,1]) + t0;

subplot(length(T),length(b), v_b + loopVar)

histogram (data)

ax = gca;

get(ax, 'position')

ax.XLim=[0,10];

end

loopVar = loopVar + length(T)

end

Hello Mustafa,

I recommend that you take a look at Mike Cohen's courses: https://www.udemy.com/course/master-matlab-through-guided-problem-solving/

I went through them last year and taught myself MATLAB in that way. I feel that you are trying to solve problems before understanding the basics of what you are doing, which could be fixed in a few hours of practice/watching courses/reading a MATLAB book.

In this case, when you plot data3p, you are overwriting all the information of data2p. You need to plot the information in a different subplot.

clear all;

n = 100;

t0 = 0.5;

b = 1:5;

T = 1:5;

for v_T = 1:length(T)

for v_b = 1:length(b)

figure(v_T) % this will count 1:5 and open a new figure each step

data2p(:,v_b,v_T) = wblrnd(v_T,v_b, [n,1]);

data3p(:,v_b,v_T) = wblrnd(v_T,v_b, [n,1]) + t0;

subplot(2,5,v_b) % subplot is bigger, 2 rows and 5 colums

histogram (data2p)

subplot(2,5,v_b +5) % you need this new subplot here

histogram (data3p)

ax = gca;

get(ax, 'position')

ax.XLim=[0,10];

end

end

You did not put in

hold on

Well you can use subplot() or you can use the newer tiled layout operations, if you want all the histograms to appear in the same figure but diffrent axes.

Or you can add a call to figure() to create a new figure each time.
