Pull Value from MATLab Matrix: Solve the Problem

[Ethers0n]

Does anyone know how to pull the value of an element which has been calculated and placed in a matrix out of the matrix?

ie.

M = [a1, a2;
b1, b2];

c = a1*3;

?

I can't seem to find any information online...

Thanks.

You reference elements like this:

Given any matrix

M=[a1,a2,a3,...,an;
         .
         .
         .
   m1,m2,m3,...,mn]

an element is accessed by referenceing its row and column position. So,
M(c,10) would return the element loacted in the third row, 10th column.

To pull the value of an element from a matrix in MATLAB, you can use indexing. In this case, you can use the variable "c" to access the calculated value of a1*3. For example, if you want to access the value of a1*3, you can use M(1,1) since a1 is located in the first row and first column of the matrix. So, the code would be M(1,1) = c. This will replace the value of a1 in the matrix with the calculated value. You can also store the calculated value in a new variable by using the assignment operator, like c = M(1,1). This will create a new variable containing the value of a1*3. I hope this helps.
