OZ: Title Ozawa model crystallization

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
