Matlab matrix

Example: h = @(x)sin(x) M — Symbolic matrix variable to convert symbolic matrix variable Symbolic matrix variable to convert, specified as a symbolic matrix variable. Alternatively, you can use symmatrix2sym to convert a symbolic matrix variable to an array of symbolic scalar variables. Example: syms A 2 matrix; M = A^2 + eye(2) Data Types: symmatrixOutput Argumentscollapse allx — Variable symbolic scalar variableVariable, returned as a symbolic scalar variable.A — Vector or matrix with automatically generated elements symbolic vector | symbolic matrixVector or matrix with automatically generated elements, returned as a symbolic vector or matrix of symbolic scalar variables. The elements of this vector or matrix do not appear in the MATLAB workspace.symexpr — Expression or matrix converted from anonymous MATLAB function or symbolic matrix variable symbolic expression | symbolic matrix Expression or matrix converted from an anonymous MATLAB function or a symbolic matrix variable, returned as a symbolic expression or matrix of symbolic scalar variables. Data Types: symTipsStatements like pi = sym(pi) and delta = sym("1/10") create symbolic numbers that avoid the floating-point approximations inherent in the values of pi and 1/10. The pi created in this way stores the symbolic number in a workspace variable named pi, which temporarily replaces the built-in numeric function with the same name. Use clear pi to restore the floating-point representation of pi.sym always treats i incharacter vector input as an identifier. To input the imaginary number i,use 1i instead.clear x does not clear the symbolicobject of its assumptions, such as real, positive, or any assumptionsset by assume, sym, or syms.To remove assumptions, use one of these options:assume(x,"clear") removes all assumptions affecting x.clear all clears all objects inthe MATLAB workspace and resets the symbolic engine.assume and assumeAlso provide more flexibility for setting assumptions on variables.When you replace one or more elements of a numericvector or matrix with a symbolic number, MATLAB converts thatnumber to a double-precision number.A = eye(3);A(1,1) = sym(pi)A = 3.1416 0 0 0 1.0000 0 0 0 1.0000 You cannot replace elements of a numeric vector or matrix with a symbolic variable, expression, or function because these elements cannot be converted to double-precision numbers. For example, A(1,1) = sym("a") throws an error.When you use the syntax A = sym("a",[n1 ... nM]), the sym function assigns only the symbolic array A to the MATLAB workspace. To also assign the automatically generated elements of A, use the syms function instead. For example, syms a [1 3] creates the row vector a = [a1 a2 a3] and the symbolic variables a1, a2, and a3 in the MATLAB workspace.Alternative FunctionalityAlternative Approaches for Creating Symbolic VariablesTo create several symbolic variables in one function call, use syms. Using syms also clears assumptions from the named variables.Version HistoryIntroduced before R2006aexpand allR2022b: Convert symbolic matrix variablesYou can convert a symbolic matrix variable M of type symmatrix to an array of symbolic scalar variables symexpr of type sym by using symexpr = sym(M). For an example, see Convert Hessian Matrix.R2020a: sym("pi") creates symbolic variablesym("pi") now creates a symbolic variable

MATLAB is an abbreviation for "matrix laboratory." While other programming languages mostly work with numbers one at a time, MATLAB® is designed to operate primarily on whole matrices and arrays.All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra.Array CreationTo create an array with four elements in a single row, separate the elements with either a comma (,) or a space.This type of array is a row vector.To create a matrix that has multiple rows, separate the rows with semicolons.a = [1 3 5; 2 4 6; 7 8 10]a = 3×3 1 3 5 2 4 6 7 8 10You can also define each row on its own line of code and separate the rows with a newline.a = 3×3 1 3 5 2 4 6 7 8 10Another way to create a matrix is to use a function, such as ones, zeros, or rand. For example, create a 5-by-1 column vector of zeros.Matrix and Array OperationsMATLAB allows you to process all of the values in a matrix using a single arithmetic operator or function.ans = 3×3 11 13 15 12 14 16 17 18 20ans = 3×3 0.8415 0.1411 -0.9589 0.9093 -0.7568 -0.2794 0.6570 0.9894 -0.5440To transpose a matrix, use a single quote ('):ans = 3×3 1 2 7 3 4 8 5 6 10You can perform standard matrix multiplication, which computes the inner products between rows and columns, using the * operator. For example, confirm that a matrix times its inverse returns the identity matrix:p = 3×3 1.0000 0.0000 -0.0000 0 1.0000 -0.0000 0 0.0000 1.0000Notice that p is not a matrix of integer values. MATLAB stores numbers as floating-point values, and arithmetic operations are sensitive to small differences between the actual value and

MATLAB vs Mathematica is always a crucial battle for statistics students.They always wanted to know that which one is better between MATLAB vs Mathematica.
