Help with rtitr error in Scilab

[Nick Othieno]

Hi guys,

I am trying to run the following code in scilab:


L=3; M=2; fs_in=6; Ts_in=1/fs_in;
t_in=[0:Ts_in:5];x_in=sin(2*%pi*t_in)+2*cos(4*%pi*t_in);
getf("spfsr.sci");
getf("firpm.sci");
x_e=expander(x_in,L);
t_cont=[0:0.01:5]; x_cont=sin(2*%pi*t_cont)+2*cos(4*%pi*t_cont);
h=L*firpm(60,[0 2/(fs_in*L) 4/(fs_in*L) 0.5]*2,[1 1 0 0],[1 1]);
x_ef=rtitr(h,1,x_e);

but I get the following error:


-->x_ef=rtitr(h,1,x_e);
                           !--error 60
argument with incompatible dimensions


The values in x_e are:

-->x_e
 x_e  =


         column  1 to 14

Does anyone have any idea as to why rtitr is giving me the error?


-->x_ef=rtitr(h,1,x_e);
                           !--error 60
argument with incompatible dimensions
