how can i convert a vector into a scalar in Simulink?

i wanted to use the 'if' block in my simulink project but the input data found to be a vector value. but the value needs to be a scalar instead of a vector. so, how can i convert this a 2x200 vector matrix into a scalar or is there any other solution?

Thanks!

Hi @bitec bit,

I see that you want to convert your vector data into a scalar value.

There is no fixed way to convert vector data which is 2x200 which means we are talking about 400 values into a single scalar value. It will by and large depend upon what you want to do. You can get a scalar by simply summing up all the values or taking average of all the values. It will depend upon the end result that you want.

You can refer to this MATLAB Answer in which user wants to convert vector to scalar but end expectation from the scalar is clear: https://www.mathworks.com/matlabcentral/answers/563684-convert-vector-into-scalar-simulink

In the "if" block of Simulink, you can use multiple values from the vector by combining them into a complex condition using relational operators. With reference to using values from the vector in "if" block of Simulink, refer to this MATLAB Answer: https://www.mathworks.com/matlabcentral/answers/225254-is-it-possible-to-have-a-vector-input-to-a-simulink-if-statement-block

Kindly refer to the documentation of "if" block to gain more insights: https://www.mathworks.com/help/releases/R2021a/simulink/slref/if.html

I hope this will help!
