示例：单选按钮

可通过此脚本控制基于特定 Seed 值生成一组随机数字的过程。

1. 定义变量和 Seed 函数。

<region id="ID0EEI3OB" actualWidth="358.32666666666671" actualHeight="70.800000000000011" top="268.80000000000007" left="57.600000000000009" xmlns="http://schemas.mathsoft.com/worksheet50">
  <math resultRef="22">
    <define xmlns="http://schemas.mathsoft.com/math50">
      <function>
        <id labels="VARIABLE" xml:space="preserve">DiffNormal</id>
        <boundVars>
          <id labels="VARIABLE" xml:space="preserve">n</id>
          <id labels="VARIABLE" xml:space="preserve">μ</id>
          <id labels="VARIABLE" xml:space="preserve">σ</id>
          <id labels="VARIABLE" xml:space="preserve">s</id>
        </boundVars>
      </function>
      <program>
        <apply>
          <id labels="FUNCTION" xml:space="preserve" label-is-contextual="true">Seed</id>
          <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">s</id>
        </apply>
        <localDefine>
          <id labels="VARIABLE" xml:space="preserve">nums</id>
          <apply>
            <id labels="FUNCTION" xml:space="preserve" label-is-contextual="true">rnorm</id>
            <sequence>
              <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">n</id>
              <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">μ</id>
              <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">σ</id>
            </sequence>
          </apply>
        </localDefine>
        <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">nums</id>
      </program>
    </define>
    <resultFormat>
      <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" />
    </resultFormat>
  </math>
</region>

2. 在输入/输出选项卡的控件组中，单击高级 > 单选按钮。

3. 为定义运算符左侧的单选按钮输入输出变量名。

4. 在单选按钮的右侧添加项列表。在本例中，此列表为 Seed 值列表。

a. 右键单击单选按钮，然后选择编辑。

b. 单击属性选项卡。

c. 编辑单选按钮的值。

d. 单击关闭。

5. 也可使用脚本编辑器编辑脚本。

将此示例复制到 PTC Mathcad Prime 工作表中，以查看此处使用的脚本。

6. 定义绘图函数。

<region id="ID0EF13OB" actualWidth="196.09666666666666" actualHeight="25.6" top="787.20000000000016" left="19.200000000000003" xmlns="http://schemas.mathsoft.com/worksheet50">
  <math resultRef="33">
    <define xmlns="http://schemas.mathsoft.com/math50">
      <function>
        <id labels="VARIABLE" xml:space="preserve">F</id>
        <boundVars>
          <id labels="VARIABLE" xml:space="preserve">x</id>
        </boundVars>
      </function>
      <apply>
        <mult />
        <apply>
          <mult />
          <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">n</id>
          <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">h</id>
        </apply>
        <apply>
          <id labels="FUNCTION" xml:space="preserve" label-is-contextual="true">dnorm</id>
          <sequence>
            <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">x</id>
            <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">μ</id>
            <id labels="VARIABLE" xml:space="preserve" label-is-contextual="true">σ</id>
          </sequence>
        </apply>
      </apply>
    </define>
    <resultFormat>
      <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" />
    </resultFormat>
  </math>
</region>

7. 绘制每个种子值的分布图，以查看不同单选按钮值的变化。
