S3L_read_array and S3L_read_sub_array accept the following arguments as input:
a - S3L array handle for the parallel array to be read. This array handle was returned when the array was declared.
lbounds - Integer vector specifying the lower bounds of the indices of a along each of its axes.
ubounds - Integer vector specifying the upper bounds of the indices of a along each of its axes.
strides - Integer vector specifying the strides on the indices of a along each of its axes.
filename - Scalar character variable specifing the name of the file from which the parallel array will be read.
format - Scalar character variable specifing the format of the data to be read. The value can be either "ascii" or "binary".
