A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns. The elements can be numbers, logical values (true or false), dates and times, strings, categorical values, or some other MATLAB data type. Even a single number is stored as a matrix. For example, a variable containing the value 100 is stored as a 1 ...
You can concatenate two matrices to create a larger matrix. The pair of square brackets ' []' is the concatenation operator. MATLAB allows two types of concatenations −. Horizontal concatenation. Vertical concatenation.
Learn to create arrays in MATLAB with concatenation to build new matrices from existing ones, array creation functions, reshaping arrays, and indexing to extract submatrices.
How can I combine two matrices ?. Learn more about combine matrix A = [1 2 3; 4 5 6; 7 8 9] B = [10 11 12; 13 14 15] C = [1 2 3; 4 5 6; 7 8 9; 10 11 12; 13 14 15]
Jun 23, 2013 · Columns 2 and 3 are actually same numbers, BUT with difference order. How can I merge them together? For example, column 2 of matrix A is [a b c d e f]' and column 3 of matrix B is [d c b a e f]'. All the letters are unique ones. Is there an easy way to merge A and B?
Feb 8, 2017 · For example: A = [0 0 0 0 0 0 0 10 20; 0 0 0 0 0 0 1 30 40]; B = [0 0 0 0 0 0 0 50 60]; A merged matrix would look like this: C = [0 0 0 0 0 0 0 10 20 50 60; 0 0 0 0 0 0 1 30 40 0 0]; As you can see, the first row of C has columns 8, 9 from matrix A and columns 10,11 from matrix B.
