Multiplying multiple renamed matrices

[jono05]

I have a problem multiplying 'n' number of matrices which are output from a for loop within a for loop.

I am using the code "eval(['matrix' num2str(t) '= [A,B;C,D]')] to each matrix with their respective frequency number (t) on the end and then repeat the loop. i.e if there was frequency from 1-3 it would output
matrix1=[values of A,B,C,D at that frequency]
matrix2=[ ]
matrix3=[ ] ect

These matrix(t) then have to all be multiplied together to create a transfer matrix which is also 2X2 i.e matrix1*matrix2*matrix3.

can anyone tell me how to word this so i can get the output after the loop to multiply from matrix(1) to matrix(t) together? The variables are not stored in numerical order meaning an array is not possible.
Anyone got any ideas? if I'm not wording this clearly enough please say and i'll try to be mo precise.

thanks.

One possible solution would be to use a for loop to iterate through each matrix and then use the dot product operator (.*) to multiply them together. For example:total_matrix = matrix1;for t = 2:n total_matrix = total_matrix.*matrix(t);endThis will multiply all of the matrices together in the order they are given and then store the result in total_matrix.

I would suggest breaking down the problem into smaller steps and clearly defining your variables. It seems like you have a for loop within a for loop, which can make the code more complex and difficult to understand. Instead, you could try creating a single for loop that iterates through all the matrices and multiplies them together.

Additionally, it might be helpful to store the matrices in an array or data structure, rather than using a variable with a frequency number at the end. This would make it easier to access and manipulate the matrices in your code.

Lastly, make sure to clearly define your desired output and any constraints or limitations you may have. This will help others understand your problem and provide more specific solutions.
