The command syms A will create symbolic variable ‘A’ & will automatically assign it to MATLAB variable with same name.

Please keep in mind that we are using the ‘syms’ function here so that the variable is created dynamically. In the first example, we will use syms function to create a variable. Let us now understand the code to use syms in MATLAB. Please note that a single call can be used to create more than one symbolic function.

syms f(variable1, vaiable2, …., variableN)is used to create the symbolic function & symbolic variables which will represent input arguments of function ‘f’.

Each of the array will have the size n1- X -…- X -nM & will contain automatically generated symbolic variables. variableN is used to create symbolic arrays variable1 …. ‘syms’ function will clear all the assumptions from variables.

syms variable1 variable2 …… variableN is used to create symbolic variables variable1 … variableN.

Syms f(variable1, variable2, …., variableN) I am extremely confused why syms gets built using the values I have manipulated previously.Īny and all help would be greatly appreciated.Hadoop, Data Science, Statistics & others That is not the value of syms the value of syms outputs I have tried to mess with this but based on how I have previously declared b as a syms I am having a hard time manipulating this variable. Then thirdly I want to substitute the variable value of b for the value of b_prime*cos(40). So b would no longer be a symbol and I can set the value of b, allowing Vzx1_num to ouput the value of Vzx1 with b replaced with a number. So secondly, I would like to ouput the numerical value of these generated expression by using the value of b. The error lies in how I would like to manipulate the value I have generated. This part works perfectly for what I am intending to do.

The first syms (syms = x Wg Iyy b), I would like to keep as is because based on my needs I want to output the value of Vzx1 in terms of those variables. So to expand on more what is going on and what I am looking to do. % Not really sure how to do this, I know I have to redclare the syms % Get the numerical output of the value using b as wing This is a little difficult for me to explain without including my code firsts so: syms x Wg Iyy b I am wanting to do something with two separate set of syms and manipulate the syms.
