Converting Mat Into Single Matrix

If dim is a scalar then c contains numel a size a dim cells.

Converting mat into single matrix.

If t is an m byn table with variables that each have one column then each variable becomes one column in a and a is an m by n array. But the resulting 2 matrices are s4 object of class. I ve looked around and i must be missing it because it s probably somewhere. Matrix mkmat convert variables to matrix and vice versa 5 svmat example 2 let s get the vector of coefficients from a regression and use svmat to save the vector as a new variable save the dataset load the dataset back into memory use mkmat to create a vector from the variable and finally use matname to rename the columns of the row.

If dim is not specified then c is the same size as a. None of the provided examples here work for the generic case which are n dimensional matrices. The matrix header. The matrix header containing information such as the size of the matrix the method used for storing at which address is the matrix stored and so on and a pointer to the matrix containing the pixel values taking any dimensionality depending on the method chosen for storing.

Here is another possible solution assuming matrix have one column you can reshape original mat to one column mat via reshape. Mat is basically a class with two data parts. For example if a is a 10 by 10 matrix then reshape a 2 2 reshapes the 100 elements of a into a 2 by 2 by 25 array. If t contains variables that consist of more than one column those variables become multiple columns in a and the size of a is greater than the size of t.

You can specify a single dimension size of to have the dimension size automatically calculated such that the number of elements in b matches the number of elements in a. If dim is 1 or 2 then each cell contains a column or row vector respectively. Single precision variables in matlab are stored as 4 byte 32 bit floating point values of data type class single. If t contains variables with more than two dimensions the number of dimensions of a is the same as.

I read the data in using temp readmat movielens mat where readmat is from the r matlab package. I can send someone the data if they need it but it s too big to include here. For example to convert 1 2. If dim 2 then each cell contains an array whose dimth dimensional length is size a dim and whose other dimensions are all singletons.

Hi i have to convert a matrix in one column row vector composed of all the rows of the original matrix.
