Creat 1000 different matrix
1 回表示 (過去 30 日間)
古いコメントを表示
I have 1000 different values of Bi, I want to creat 1000 different C matrix of order (12, 1) , where Each element of (12, 1) , ist matrix contains ist value of Bi and each element of (12, 1) ,2nd matrix contains 2 nd value of Bi. and so on. And each different 1000 matrix will print in Command windows and it's name like C1, C2, C3... C1000.

Can you define variables with numbered names like C1, C2, C3, ... ? Yes.
Should you do this? Generally we recommend against it. See that page for alternatives you should use instead.

Okay Steven, instead of C1, C2.. C1000 you can take C(1), C(2).. C(1000).and please help in this code

@Deepesh Kumar Gupta: either use a cell array to hold all of those matrices:
or one numeric ND-array:
What did you try so far?

I have to print all 1000 matrix in command window.
Thank you in advance

c=0.01;
d=.013;
m=1000;
ri=c+(d-c).*rand(m,1);
h=315;
K=44.5;
Bi=(h*ri) /K;
for k=1:1000
C=zeros(12,1)
for i=1:12
C(i,:)=Bi(k)
end
end

c = 0.01;
d = 0.013;
m = 1000;
ri = c+(d-c).*rand(1,m);
h = 315;
K = 44.5;
Bi = (h*ri)./K
Bi = 1×1000

I have 1000 Rs matrix of order(1,12) and 1000 values Bi .I want to create 1000 A matrix of order (12,12). How can I create A matrix .
% matrix calculation for i=1:1000 A=zeros(12,12);
for k=1:12 for j=1:12 if j==1 A(k,j)=1./(Rs{i}(k))+Bi(i).*log(Rs{i}(k)); else A(k,j)=((j-1)*((Rs{i}(k)).^(j-1)+(Rs{i}(k)).^(1-j))./Rs{i}(k)+Bi(i)*((Rs{i}(k)).^(j-1)-(Rs{i}(k)).^(1-j)))* cos((j-1).*g(k)); end end end end

@Deepesh Kumar Gupta: please format your code properly. Badly formatted code discourages people from helping you.
% matrix calculation for i=1:1000 A=zeros(12,12);
for k=1:12
for j=1:12
if j==1
A(k,j)=1./(Rs{i}(k))+Bi(i).*log(Rs{i}(k));
else
A(k,j)=((j-1)*((Rs{i}(k)).^(j-1)+(Rs{i}(k)).^(1-j))./Rs{i}(k)+Bi(i)*((Rs{i}(k)).^(j-1)-(Rs{i}(k)).^(1-j)))* cos((j-1).*g(k));
end
end
end
end
If this code works and you need to repeat it 1000 times, then you can simply nest it inside another loop and either:
- assign the matrices to a cell arraz, much like you are already doing for Rs, or
- assign the matrices to one ND array.
Give it a try, e.g. cell array (just like Rs):
N = 1000;
C = cell(1,N);
for ii = 1:N
.. your code
C{ii} = your matrix
end
