# count rows matlab

## Summary

The number of rows in a matrix can be determined using the size function. 1 The output of the size function is a vector containing the number of rows and columns. 1 Additionally, the sum() function can be used to count the number of specific values in a matrix 2 , or the nnz() function can be used, which is more efficient than converting logicals to numeric. 2
