---------------v-aaa-lawson-------------
Summary:
v-aaa-lawson is a AAA-type method with Lawson's iteration; it produces
vector-valued or matrix-valued rational approximants as well as the
corresponding poles and zeros of user-specific rational types.
Function:
[Rfun, mJ, J, pol, zers, errA ] = v_aaa_lawson(t, bigF, nd, deg_vec, maxItr)
