Software metrics are numerical representation of some aspects of software or process of it's development
Test Engineer and Test Lead will collect the software metrics.

Having a lack of metrics, for software engineering, may cause issues for clients that require metrics for their business project. It is common in other engineering related disciplines to have metrics to show progress schedule and report. These metrics may aid in meeting deadlines and receiving payment. Not having them may cause issues in the future for software engineers and project managers.
Correct definition of metrics will help validate the goal of the software process and how that is being tracked
Metric is a measurement that can classify software or product quality and then process the quality of metrics. Matrix is a data collection mechanism, that uses collected data to derive metrics.
Use Metrics to Manage
One can effectively measure software quality by using metrics such as code complexity, code coverage, defect density, and user satisfaction. These metrics help assess the reliability, maintainability, and usability of the software, providing insights into its overall quality.
use metrics
Process metrics are used to make strategic decisions about how to complete the common process framework activities. Project metrics are used to monitor progress during software development and to control product quality.
Lines of code and function points were described as measures from which productivity metrics can be computed. LOC and FP data are used in two ways during software project estimation: (1) as an estimation variable to "size" each element of the software and (2) as baseline metrics collected from past projects and used in conjunction with estimation variables to develop cost and effort projections.
When relating to a computer, a metric is the measurement of software. Matrix is the word for a two dimensional array.
