At one of the two inputs of the multiply block connect the right shift register, and the output of this block connect the right shift register.

For the multiplication task place a multiply block, from the function palette select numeric and then select multiply as shown in the figure below,

Do overcome this ambiguity we use 1 as an initial condition.If we use 0 here as the initial condition then the shift register will multiply the 0 with all the previous products and the result of factorial will be 0. You might be wondering that we used 0 as the initial value of shift register in case of addition but now we are using 1, what is the difference.Place this numeric with the shift register and set its value to 1 as shown in the figure below,.From the function palette select numeric and then select constant as shown in the figure below, As we have already discussed in previous tutorial we must have to initialize the shift register.Click right on the boundary of the for loop and from the drop down menu select ad shift register as shown in the figure below, We can do so by using shift registers as we have used in previous tutorial. But how can we access the previous value of the product?. If we are willing to multiply all previous number of a numeric integer which is the demand of factorial calculations we will need the previous product value of the loop.We can also use while loop as we used in the previous tutorial of sum calculation, its’ up to us which loop we prefer.

number of loops of for loop as shown in the figure below, Connect the numeric control in which the user input will be stored to the N i.e.On the block diagram window, from the function palette select structures and then select for loop as shown in the figure below,.In order to place the numeric control click right on the front panel from the control palette selects numeric and then selects control as shown in the figure below, First of all, create a VI as we have done in tutorial 1 and save it for future use as we have been doing in the entire previous tutorial. Now lets’ design a VI performing the operation described above.At the end of the tutorial you are provided with an exercise to do it by yourself.Ĭalculate Factorial of a number in LabView For example, the user enters 3 as an input value to the VI then the output of the VI will return 1*2*3 = 6 in the indicator. In this tutorial I will help you to design a VI that will take a number as input from the user and at the output it will return the factorial of that natural number.
