Qt使用Numcpp（c++版的Numpy）

Qt使用Boost_Numcpp库

(1) 下载boost_1.75.0库文件

(2) 下载Numcpp: C++ implementation of the Python Numpy library

(3) 非中文路径下新建文件夹D:_Numcpp，将boost_1.75.0文件夹中的boost文件夹复制进刚刚新建的文件夹中，并将Numcpp中的includes文件夹中的NumCpp和NumCpp.hpp复制进刚刚新建的文件夹中（无需添加环境变量）

(4) 在Qt控制台项目的配置文件.pro中，修改CONFIG += c++14，并添加库文件路径，配置文件.pro内容如下：

QT -= gui

CONFIG += c++14 console
CONFIG -= app_bundle

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

TRANSLATIONS += \
    Boost_Numcpp_Test_zh_CN.ts

# Boost库文件路径添加
INCLUDEPATH += D:\Boost_Numcpp

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

(5) 测试代码

boost::timer tmr;
qDebug() << tmr.elapsed() << "S" << endl;
qDebug() << BOOST_VERSION << endl;
qDebug() << BOOST_LIB_VERSION << endl;
qDebug() << BOOST_PLATFORM << endl;
qDebug() << BOOST_COMPILER << endl;
qDebug() << BOOST_STDLIB << endl;

nc::NdArray<float> m1 = {{1, 2}, {3, 4}};
nc::NdArray<float> m2 = {{1, 2}, {3, 4}};
nc::NdArray<float> m3 = m1 * m2;
std::cout << m3 << std::endl;
return a.exec();
