Convert Vector To Matrix Octave

Return true if the vector part of quaternion q is zero and false otherwise.

Convert vector to matrix octave. Convert the cell array c into a matrix by concatenating all elements of c into a hyperrectangle. 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. 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. And cat must be able to concatenate them together.

Vectors are a special case of a matrix where there is only one row a row vector or only one column a column vector. Octave supports various kinds of conversions between strings and numbers. S prime 0 1 1 0 1 1 1 1. You can work with parts of matrices and vectors by indexing into them.

Octave is a program specially designed for manipulating matrices. Numbers are also a special case of a matrix as octave regards them as 1 by 1. 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. If s is a string matrix return a column vector with one value per row of s.

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. Here is the small code snippet and the expected result. If i need to convert 12x1 vector into 3x4 matrix what should i do. Return the vector obtained by eliminating all superdiagonal elements of the square matrix x and stacking the result one column above the other.

Prepad x l. How can i do this. Octave forge is a collection of packages providing extra functionality for gnu octave. As an example it is possible to convert a string containing a hexadecimal number to a floating point number.

Active 2 years 5 months ago. Elements of c must be numeric logical or char matrices. Hex2dec ff 255. This has uses in matrix calculus where the underlying matrix is symmetric and it would be pointless to keep values above the main diagonal.

For example to convert 1 2. Prepad x l c. Hi i have to convert a matrix in one column row vector composed of all the rows of the original matrix. That is prod sz must be the same as numel a.

Convert 3x3 rotation matrix r to unit quaternion q. I tried using reshape but i was not successful. Output size specified as a row vector of integers. You use a vector of integers to tell octave which elements of a vector or matrix to use.

S 0 1 1 0 1 1 1 1 expected result.
