mjf和jmeasfcn在matlab的区别

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：

<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。
