Starink: Title Staink

In takos: Analysis of Differential Calorimetry Scans

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
