请通过示例提醒我什么是floar [] []输入。 [英] Please remind me what is a floar[][] input with examples.

问题描述

我正在尝试运行代码，但由于我没有练习一段时间，我忘记了一些输入。一个例子是float [] []输入，我应该为此输入什么？



代码示例：

I am trying to run a code, but since I don't practice for a while I have forgotten some of the inputs. one example is float[][] input, what should I enter for this?

Code example:

public double[][] forwardDCT(final float input[][]) {
      final double output[][] = new double[this.N][this.N];
      double tmp0, tmp1, tmp2, tmp3, tmp4, tmp5, tmp6, tmp7;
      double tmp10, tmp11, tmp12, tmp13;
      double z1, z2, z3, z4, z5, z11, z13;
      int i;
      int j;

我的尝试：



尝试整数64，双64.0

What I have tried:

Tried integer 64, double 64.0

public double[][] forwardDCT(final float input[][]) {
      final double output[][] = new double[this.N][this.N];
      double tmp0, tmp1, tmp2, tmp3, tmp4, tmp5, tmp6, tmp7;
      double tmp10, tmp11, tmp12, tmp13;
      double z1, z2, z3, z4, z5, z11, z13;
      int i;
      int j;
