Now that we have created our 2D array in JavaScript, let us learn what operations can be performed on this array. We would look at how to access, insert, remove and update elements in our array. So, we create an array and initialize it with values as below: var array2D = new Array(...

我的目标是在Javascript中创建一个随机生成的2D数组,它的X值是相同的一个字符值,而其余的值等于另一个字符。 在本例中,2DArray有10行10列。20数组中可能的100个值应该等于'Y‘(是的话),另外80个值应该是'N’(代表no)。我希望‘Y’被随机地放置在整个数组中,我绝对需要其中的20个是‘Y’,其余的‘N’。

这样虽然可以避免内存访问错误,但是仍有可能会生成一些无效数据。譬如,你把 JavaScript 端返回的 Float32Array 的最后 3 个元素打印出来,它们是247055、248056、608032;如何避免因数组索引越界而可能发生的无效数据问题呢?可以用卫语句提前返回: fnmain(/*...*/){if(global_id.x>=arrayLength(&output)){return;}...

ArrayType: the array type used for coordinates storage (Float64Arrayby default); other types may be faster in certain cases (e.g.Int32Arraywhen your data is integer). ArrayBufferType: the array buffer type used to store data (ArrayBufferby default); you may preferSharedArrayBufferif you want...
