How to create guide user simulink control robots 2 degrees of freedom according to the trajectory imported from the guide

I have 1 matrix n * 13 which is the coefficient of motion orbit function entered in excel I want to compare the time of clock or step block and the time in matrix will have the corresponding trajectory which seems to only receive the final value of matrix

Is there any way to change the coefficients by the time variable in step step at the same time?
