i have this matrix
PP =
11 8 2 10 1 4 6 5 9 7 12 3
4 3 5 7 6 9 11 1 2 8 12 10
4 11 9 10 12 2 6 5 8 1 7 3
3 9 2 7 6 8 11 12 1 4 10 5
i want to split this matrix into to part
so code like this
v=2
p1=[PP(1:v,:)];
p2=[PP(PP-v+1:end,:)];
v=2 means that i want to split into two row..
the 1st and 2nd row is in p1, and the 3rd and 4th in p2..
for p1 i got the code correctly however for p2 i didnt get it right
i put v because if the matrix change to 6x6 or 10x10 , i want to change the value of v into what ever i want..

Don’t think of naming variables dynamically ( https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval#answer_274740 )
v=2;
P=reshape(PP,v,size(PP,2),[])

I have a matrix as below;
1 0.7494 -32.75 -25.375
2 0.91315 -9.875 -10.75
2 1 -3 -7.375
1 1.8799 -8.875 -5.875
2 2.29885 30.875 40.50
2 2.46570 -2.25 3.875
I would like to split it into 'n' number of matrices based on the variations in the first column. In the above example n=2.
Doese anyone know how I can do it in Matlab?
Thanks

I mean I would like to split it as the following 2 matrices
1 0.7494 -32.75 -25.375
1 1.8799 -8.875 -5.875
and
2 0.91315 -9.875 -10.75
2 1 -3 -7.375
2 2.29885 30.875 40.50
2 2.46570 -2.25 3.875

Use unique function to get the index of items from the first column. Now use that index to split your matrix.
