**How to create larger matrix within a loop? MATLAB**

The code I have works, it does what I want it to do, but it's terribly inefficent and somewhat slow for large matrices. The main reason for this inefficency is because it has to generate a new larger matrix for each iteration of the loop, because there is no value of F prealocated.... How to create a signal matrix. Learn more about for loop, signal, rule, bigger, smaller than I am only now getting to know matlab. In my rankfull2 matrix I have some NaNs that change from row to row as well. So I would like the decision criteria not to be fixed but dependent on the number of non NaNs that i have in each row. In other words, immagine the first rankfull2 row to have 600

**How to add smaller matrix into bigger matrix? (Tetris**

So, I've got an Excel file that contains a matrix that's over 50 columns wide, and a Matlab script that uses xlsread to extract that matrix and do some computations on it.... You want to take the index P(i) and grab the next 10 elements after that point, then put them into a row in M. This works fine for the first several iterations where P is picking out relatively small indices.

## How To Make A Matrix Bigger In Matlab

### The code I have works, it does what I want it to do, but it's terribly inefficent and somewhat slow for large matrices. The main reason for this inefficency is because it has to generate a new larger matrix for each iteration of the loop, because there is no value of F prealocated.

- n A row vector in MATLAB can be created by an explicit list, matrix. returns the larger of the number of rows or columns in A. Matrices (conâ€™tâ€¦) Transpose B = Aâ€™ Identity Matrix eye(n) Ã¨returns an n x n identity matrix eye(m,n) Ã¨returns an m x n matrix with ones on the main diagonal and zeros elsewhere. Addition and subtraction C = A + B more commands 12 C = A â€“B Scalar
- An array is the most fundamental data type in MATLAB. In MATLAB, as in many traditional languages, arrays are a collection of several values of the same type. The string and number data type formerly presented are particular cases of arrays. A matrix is an array with two dimensions. Most arrays have the same data type; however, a cell array is an array with varying data types. If no data type
- I want to put a small matrix (p*q) called B into a bigger matrix (m*n) called A. How can I do it. Matrix B should be put on the left-right corner of matrix A. How can I do it. Matrix B should be put on the left-right corner of matrix A.
- but I'm trying to use Matlab special features in matrix calculations to put A with local dimension in B with global dimension. because Matlab features are fast and need less code writing.
