Convert vector to matrix octave.

Hex2dec ff 255. Beyond the second dimension the output b does not reflect trailing dimensions with a size of 1 for example reshape a 3 2 1 1 produces a 3. Numbers are also a special case of a matrix as octave regards them as 1 by 1. Return the vector obtained by eliminating all superdiagonal elements of the square matrix x and stacking the result one column above the other.

For example to convert 1 2. What is the inverse operation to vec in octave. Vector to matrix in octave. This has uses in matrix calculus where the underlying matrix is symmetric and it would be pointless to keep values above the main diagonal.

S 0 1 1 0 1 1 1 1 expected result. If i need to convert 12x1 vector into 3x4 matrix what should i do. Output size specified as a row vector of integers. Hi i have to convert a matrix in one column row vector composed of all the rows of the original matrix.

Convert the cell array c into a matrix by concatenating all elements of c into a hyperrectangle. If s is a string matrix return a column vector with one value per row of s. Octave is a program specially designed for manipulating matrices. Ask question asked 8 years 4 months ago.

S prime 0 1 1 0 1 1 1 1. You use a vector of integers to tell octave which elements of a vector or matrix to use. Octave forge is a collection of packages providing extra functionality for gnu octave. How can i do this.

Viewed 9k times 6. And cat must be able to concatenate them together. As an example it is possible to convert a string containing a hexadecimal number to a floating point number. I have a mxn matrix and would like to convert into a vector mnx1 with all the elements of the row from the matrix as the elements of the vector.

Convert 3x3 rotation matrix r to unit quaternion q. Here is the small code snippet and the expected result. Each element of sz indicates the size of the corresponding dimension in b you must specify sz so that the number of elements in a and b are the same. Modulus of a quaternion.

I tried using reshape but i was not successful. You can work with parts of matrices and vectors by indexing into them. Active 2 years 5 months ago. Prepad x l c.

Return true if the vector part of quaternion q is zero and false otherwise. For example we create a vector octave 1 x 1 2 5 7 6 3 8 x 1 2000 5 0000 7 6000 3 0000 8 0000 now to see the second element of x type octave 2 x 2 ans 5. That is prod sz must be the same as numel a.

Vectors are a special case of a matrix where there is only one row a row vector or only one column a column vector.
