The Indo-US coudé feed stellar spectral library (CFLIB) published recently by Valdes et al. (2004) contains spectra of 1273 stars in the spectral region 3460 to 9464 Å at a resolution of 1 Å. About 500 stars in this database have gaps ranging from a few Å to several tens of Å in this wavelength range. We use a variation of Principal Component Analysis (PCA) technique to fill gaps of up to 5Å in a subset of spectra from the CFLIB. We hope to exploit the full potential of the scheme and attempt to fill larger gaps in stellar spectra in a subsequent study.
