Help !--error 21

[Lucas Benitez Demmler]

Hello,
I have a problem when i want to run "SPDsolver.sci"
In Scilab Console there appears after executing: 

!--error 21
Invalid index
at line         5 of function zeroslines called by:
at line         2 of function SPDverif called by:
at line         3 of function SPDsolve called by:
SPDsolve(K0,K,P,cDof,cDofasc,nn)

 
SPDsolve file use internally a function called SPDverif but i don't understand why it is not working.
Both files were translated form MATLAB to SCILAB and i use loadmatfile command to load all the variables.
I would like to know where the mistake is.
I'm sending you the .sci files for testing
 
Thanks you very much indeed
