[Scilab-users] [EXTERNAL] Count specific values in text file

[Carrico, Paul]

Hi

Is that what you're expecting i.e. a way to reshape your matrix among other things ?

A=[1 2 3 4 5 6 7 8 9 1 1 1 1 1 1 4 4 5 5 5 5 8 8];

loc = find(A == 1);
occ = size(loc, "*");
printf("Number of occurences = %d",occ);

// reshaping
B=[1 2 3 4 5 6 7 8 9 1 1 1 ;
   1 1 1 4 4 5 5 5 5 8 8 0];
[n,m] = size(B);
C = matrix(B,(n*m),1);

// then look for your specific values

Objet : [EXTERNAL] [Scilab-users] Count specific values in text file

Hello all,

Basic query. I have text files of Pi and e to a million places and I want to
scan the number for the occurrences of particular values and the separation
of those values in the number.

This code snippet works on a vector:

// create vector of elements

A=[1 2 3 4 5 6 7 8 9 1 1 1 1 1 1 4 4 5 5 5 5 8 8];

// Count number of values, e.g. 1

Val_count1= sum(A==1)

disp(Val_count1) // answer 7

I can open the text file with pinum=mopen('pi-million.txt','rt') - but does
it need to be changed to a vector where each value is an element?. At the
moment the text file is just a single line of numbers (no decimal pint at
the start (e.g. 314159...etc).

Any pointers would be good. Sorry if this is basic one!

Thanks
