谁帮我翻译一段关于matlab的文章（汗译英）

MATLAB在机械工程信号频谱分析中的应用

摘要：Matlab作为当今世界上应用最为广泛的数学软件，具有非常强大的数值计算、数据分析处理、系统分析、图形显示甚至符号运算的功能和丰富的工具箱。
本课题通过对Matlab语言和快速傅立叶变换的了解，在对常见的基础信号的数学模型进行分析的基础上，在Matlab环境下采用Matlab语言对信号进行快速傅立叶变换编程，得出连续信号取不同的采样频率和采样周期对应的快速傅立叶变换频谱图。
关键词：MATLAB 快速傅里叶变换 频谱分析

Answer 1

Abstract: Matlab as the world's most widely used mathematical software, with very powerful features, such as numerical computation, data analysis, systems analysis, graphical display and even symbolic operation. And has kinds of toolboxes .
This issue through the learning of Matlab language and Fast Fourier Transform and on the basis of carring on the analysis to the common signal's mathematical model.Uses the Matlab language under the Matlab environment to carry on the fast Fournier transformation to the signal to obtains the spectrograph of continuous signal that take the different sampling frequency and the sampling period

Answer 2

Abstract: Matlab as the world's most widely used mathematical software, with a very powerful numerical calculation, data analysis, systems analysis, graphical display and even the function of symbolic computing and rich toolbox.

This issue through the Matlab language and understanding of Fast Fourier Transform in signal on the basis of common analysis of the mathematical model, based on the environment in Matlab using Matlab language to signal Fast Fourier Transform program, a continuous signal from a different sampling frequency and sampling period corresponds to the fast Fourier transform frequency spectrum.

Keywords: MATLAB FFT spectrum analysis
