[Scilab-users] add number arrays efficiently, how?

[Rafael Guerra]

Erhy,

Your code only works if the input arrays are  oriented similiarly (both
column or row vectors).
For the following input your code would not run:

SumArr = [ 1 2 3 ];  toAdd = [ 7 8 9 10 ]';
SumArr( (length(SumArr)+1) : (length(SumArr)+length(toAdd)) ) = toAdd;
!--error 15 
Submatrix incorrectly defined.

//You could try:

function y=add_b2a(a, b)
   [mx,k]=max(size(a));
   if k==1 then
      y= [a(:); b(:)];
   else
      y= [a(:); b(:)]';
   end
endfunction

// Examples:
SumArr = [ 1 2 3 ];  toAdd = [ 7 8 9 10 ]';
add_b2a(SumArr, toAdd)
 ans  =
    1.    2.    3.    7.    8.    9.    10. 

SumArr = [ 1 2 3]';  toAdd = [ 7 8 9 10 ];
add_b2a(SumArr, toAdd)
 ans  =
    1.   
    2.   
    3.   
    7.   
    8.   
    9.   
    10.  
 
Regards,
Rafael
