RBC_Est

HI, I have some problems in running RBC_Est.
First, I could not run RBC_DataGen, then I use simuldata.m (I found it in other post). However, I cannot run RBC_Est. Matlab shows many error comments. The first one is this: “Error in metropolis_hastings_initialization (line 68)
d = chol(vv);”

Always post the files in question.
