lashblkcreate.m

基于matlab的反演程序,用于地球物理勘探中射线追踪及偏移成像程序.

function block=lashblkcreate(bname,cmnts,irc,mnems,units,values,descs)

% block=lashblkcreate(bname,cmnts,irc,mnems,units,values,descs)
%
% LASHBLKCREATE creates an LAS logical data block in a string matrix
%
% bname ... string containing the block name (no ~, it is automatically
%				prepended
% cmnts ... string matrix containing any desired comments
% irc ... row numbers for the comments lines. Refers to rows in the
%		final block
% mnems ... string matrix of mnemonics
% units ... string matrix of units
% values ... string matrix of values
% descs ... string matrix of descriptions
