OZ: Title Ozawa model crystallization

In takos: Analysis of Differential Calorimetry Scans

Description

performs analysis of the thermograms using Ozawa method

Usage

OZ(mat, n.step = 1, spks = 1, eps = 0.001)

Arguments

mat	matrix of the all the thermograms checked using the functiom mat.check
n.step	number of steps for selecting temperature ranges
spks	id of the peaks selected for applying the method
eps	tollerance for the selection process

Value

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