Reading and Writing Surfer GRD Text Format with MATLAB

This MATLAB-based solution enables efficient reading and writing of GRD format data files used in Surfer software. The implementation is particularly suitable for direct data access scenarios where interpolation is not required. Through optimized file parsing algorithms and vectorized operations, these programs achieve processing speeds tens to hundreds of times faster than Surfer's native gridding functionality while maintaining robust handling of large-volume datasets. The core functionality includes specialized routines for GRD header parsing, data matrix reconstruction, and formatted output generation. Additionally, the solution offers enhanced flexibility and customizability through configurable parameters for various data processing requirements. For users requiring high-performance processing of substantial Surfer-format data, this MATLAB GRD read/write program represents an excellent choice, featuring memory-efficient buffering techniques and support for different GRD format variations.
