blanks.m fix

[Teemu Ikonen]

Hi all,

I noticed the blanks.m function still uses the deprecated setstr() function.
Attached is a new version of blanks.m which uses the char() function and
also accepts two input arguments in order to return a string (or char)
matrix, which I happened to need. 

BTW, I get this out of char with an ND-matrix input:

octave:24> s = char(ones(3,3,3) * toascii("A"))
s =
 
 AAA
 AAA
 AAA
  
octave:25> whos s
   
*** local user variables:
    
prot  type                       rows   cols  name
====  ====                       ====   ====  ====
 rwd  string                        3      3  s
     

Is this a bug or feature?

Best wishes,

Teemu
