Starink: Title Staink

Description

performs analysis of the thermograms using Starink method

Usage

Starink(mat, degree = seq(0.2, 0.8, by = 0.05))

Arguments

mat

matrix of the all the thermograms checked using the functiom mat.check

degree

selected degrees of cristallinity for performing the analysis

Value

models "mod", datable "xy" for plot, "Ea" list of value, datatable "DT" built with the values of mat according to the specified degrees
