Hi,
I can't understand what's wrong getting this error:

Undefined function or method '_colonobj' for input arguments of type
'double' ands attributes 'sparse col real'

Complete report from shell redirected output is

Name Size Bytes Class Attributes

a 102714x102714 39459816 double sparse

b 102714x1 818272 double sparse

nv 1x1 8 double

inod 1x17119 136952 double global

vn 2x17119 273904 double global

lbn 10x221 17680 double

nbn 1x10 80 double

Error in ==> wallslip at 5
for j = 1:nv

Error in ==> main at 99
[a,b]=wallslip(a,b,nv,inod,vn,lbn,nbn);

>>

nv's type, DOUBLE, always worked when used as indice to access in
matrix (sparse).
What's wrong in this case?

Thanks in advance for comments or suggestions

Why don't you post your main function and the wallslip function, and set a
breakpoint on line 99 of main and verify using WHOS that the information you
posted about your variables is correct?
