1. 创建子VI计算两个输入向量A和B内积。要求程序能够判断两个向量的元素个数是否相等，相等则计算内积，否则利用beep.vi报警并且弹出对话框提示。将VI计算结果和数学函数的计算结果做比较，仔细检查计算程序。



2. 创建VI，计算并绘制二阶多项式y = Ax2 + Bx + C。VI应使用前面板控件来输入系数A，B和C，并使用前面板控件输入点数N，计算x0到xN-1区间上的多项式。在波形图上绘制y-x图形指示器。

-1. Calculated to create sub-VI two input vectors A and B inner product. Required procedures to determine the number of elements of two vectors are equal, equal, the calculation of the product, or use the alarm and pop-up dialog box prompts beep.vi. The VI calculations and mathematical functions to compare the results, carefully check the computer program. 2. Create VI, calculate and draw the second order polynomial y = Ax2+ Bx+ C. VI front panel controls should be used to enter the coefficients A, B and C, and use the front panel control input points N, calculate x0 to xN-1 interval polynomial. Yx draw the waveform graph indicator.
