d4.09.04 sd_interspectrum data structure

Summary:

The sd_interspectrum data structure contains the components of an interspectral matrix or time functions produced by GENE_FONC_ALEA. Each term in this matrix is a function that depends on frequency or time. This function is real if it is an autospectrum (diagonal term of the matrix) or a temporal function, it is complex if it is an interspectrum (extra-diagonal term).

This data structure is used by the following operators: CALC_INTE_SPEC, DYNA_ALEA_MODAL, PROJ_SPEC_BASE,,,, REST_SPEC_PHYS, DEFI_SPEC_TURB,,, DYNA_SPEC_MODAL, GENE_FONC_ALEA, POST_DYNA_ALEA, CALC_ESSAI, CALC_SPEC, and DEFI_INTE_SPEC DYNA_ISS_VARI LIRE_INTE_SPEC.
