mjf和jmeasfcn在matlab的区别
时间: 2024-06-03 10:11:47 浏览: 43
mjf和jmeasfcn都是MATLAB中的函数,但是它们的功能不同:
- mjf是MATLAB中的一个函数,用于计算多元高斯分布的概率密度函数值,其中mjf代表“多元高斯分布函数”(Multivariate Gaussian Function)。
- jmeasfcn是MATLAB中的一个函数,用于定义优化问题中的目标函数或非线性约束函数。其中jmeasfcn代表“测量函数”(Measurement Function)。
因此,两个函数的用途和功能是不同的。

可以在 `buttonStyle` 对象中设置每个按钮的默认样式,然后在模板中使用 `v-bind:class` 绑定样式类即可。可以尝试以下代码:
```html
<template>
<div class="Home">
<div class="index" id="mapTree"></div>
<div class="top">
<div class="topLeft">
<div
:class="{ redText: buttonStyle['Rail'] }"
@click="toggleComponent('Rail')"
>
<a>电子围栏</a>
</div>
<div
:class="{ redText: buttonStyle['Video'] }"
@click="toggleComponent('Video')"
>
<a>视频监控</a>
</div>
<div
:class="{ redText: buttonStyle['Location'] }"
@click="toggleComponent('Location')"
>
<a>实时定位</a>
</div>
<div
:class="{ redText: buttonStyle['Monitor'] }"
@click="toggleComponent('Monitor')"
>
<a>环境检测</a>
</div>
</div>
<div class="topRight">
<div>2</div>
<div>2</div>
<div>2</div>
<div>2</div>
</div>
</div>
<Rail v-if="currentComponent === 'Rail'" />
<Video v-if="currentComponent === 'Video'" />
<Location v-if="currentComponent === 'Location'" />
<Monitor v-if="currentComponent === 'Monitor'" />
</div>
</template>
<script>
import Rail from "@/views/rail/rail.vue";
import Video from "@/views/video/video.vue";
import Location from "@/views/location/location.vue";
import Monitor from "@/views/monitor/monitor.vue";
let viewer;
Cesium.Ion.defaultAccessToken =
"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiJlYzc0OGZjYi03NDY5LTRmMmQtYTc2YS05ZTY2YzZlMTRmYTQiLCJpZCI6MTM5MzQ0LCJpYXQiOjE2ODQzMTI2MjF9.nNF8IyvsjDSdeRJeea8ftf4TC1DOgSa_jue-ZZ0dZ8M";
export default {
name: "MineHome",
components: {
Rail,
Video,
Location,
Monitor,
},
data() {
return {
currentComponent: "Rail",
currentTab: "", // 记录当前选中的按钮
buttonStyle: {
// 记录按钮样式
Rail: true,
Video: false,
Location: false,
Monitor: false,
},
};
},
mounted() {
this.toggleComponent("Rail");
this.initMap();
},
methods: {
// 初始化地图
initMap() {
viewer = new Cesium.Viewer("mapTree", {
infoBox: false, // 禁用infoBox
});
// 加载倾斜模型
var tileset = new Cesium.Cesium3DTileset({
url: "http://47.104.159.54:8156/out2/tileset.json",
});
viewer.scene.primitives.add(tileset);
viewer.zoomTo(tileset);
},
toggleComponent(componentName) {
this.currentComponent = componentName;
// 更新按钮样式
for (let key in this.buttonStyle) {
this.buttonStyle[key] = key === componentName;
}
},
},
};
</script>
<style>
.redText {
color: red;
}
</style>
```
这里使用了 `v-bind:class` 动态绑定样式类,当 `buttonStyle` 对象中对应的属性为真时,元素会添加 `redText` 样式类,从而显示为红色字体。在 `toggleComponent` 方法中,更新当前组件并更新按钮样式。注意还需要添加 `.redText` 样式定义才能实现红色字体。
sm2 pem文件示例
以下是一个示例的SM2私钥的PEM文件内容:
```
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHcCAQEEIEMj6zWz/5wQSnvZD4rKKJo4l9qEf8X6g7oSISNQ0s3QoAoGCCqBHM9

G1xk5Pz2EsK0Wg2S8/B2HImM9j/7KxqJhg==
-----END EC PRIVATE KEY-----
```
请注意,这只是一个示例私钥文件,实际文件的内容会根据具体的私钥生成工具和库而有所不同。您可以使用类似的格式将私钥保存到一个文本文件中,并确保文件以`.pem`为扩展名。
希望这个示例对您有所帮助!如果您有任何其他问题,请随时提问。
