trials = cumfit(Nind) / NSel * (rand + (0:NSel-1)')

这是一段代码，看起来是在进行某种试验的计算。根据代码的结构，我推测 `cumfit(Nind)` 是一个函数，它可能计算了个体适应度的累积值。`NSel` 是选择的个体数量，`rand` 是一个随机数，`(0:NSel-1)'` 则是一个从 0 到 `NSel-1` 的向量。整个表达式的含义是将 `cumfit(Nind)` 的结果除以 `NSel`，然后乘以一个随机数和从 0 到 `NSel-1` 的向量。这可能是在进行某种试验的随机抽样或计算。

这段错误信息表明在执行脚本时发生了一个检查失败的情况。错误的具体位置在 `base_map_node_index.cc:101`。可能的原因包括：

1. 数据不匹配：脚本中使用的数据可能存在不匹配的情况，例如字段名或者数据格式不正确。

2. 数据文件缺失：脚本所需的某些数据文件可能不存在或者路径不正确。

3. 依赖问题：脚本所依赖的某些组件或库可能缺失或者版本不兼容。

请检查脚本 `scripts/msf_create_lossless_map.sh` 中的相关代码，确保数据文件和依赖项的正确性。如果问题仍然存在，您可以提供更多的上下文信息，以便我们能够更好地帮助您解决问题。

这段代码似乎是关于自动驾驶系统中的地图构建和定位相关的内容，其中使用了Velodyne激光雷达获取点云数据，并将其加载到地图中。但是在处理过程中出现了一些错误，如无法匹配点云数据中的“强度”和“时间戳”字段等。最终，程序在执行到 base_map_node_index.cc 文件的第101行时，因为检查失败而发生了错误。需要进一步分析代码和数据，找出具体的问题所在并进行修复。
