Setting time-dependent boundary condition

I'm new to COMSOL and I have a problem which must be very easy to professionals while confusing for me.
Here is my problem:
I want to solve a 2D acoustic model with the method of transient analysis because one of the boundaries on the geometry should be fed a time-dependent pressure wave. However, the time-dependent pressure wave is in the form of a MATLAB m x 1 column vector where m denotes the number of time steps. In this situation, how can I set the boundary condition of the wave input boundary so that the pressure column vector is imported to the boundary?
I've looked up the manual "MATLAB Interface Guide" but couldn't find how to import vectors from MATLAB to COMSOL. Could someone please tell me how?
Thanks very much in advance!
Maximus
ps. the attachment shows where I'm stuck! I want to replace the scalar variable "p_i_acpr" with my own column vector.
