FAQs

Is there a simplify function in MATLAB? ›

S = simplify( expr ) performs algebraic simplification of expr . If expr is a symbolic vector or matrix, this function simplifies each element of expr . S = simplify( expr , Name,Value ) performs algebraic simplification of expr using additional options specified by one or more Name,Value pair arguments.

simplifyFraction( expr ) simplifies the rational expression expr such that the numerator and denominator have no divisors in common. simplifyFraction( expr ,'Expand',true) expands the numerator and denominator of the resulting simplified fraction as polynomials without factorization.

y = downsample( x , n ) decreases the sample rate of x by keeping the first sample and then every n th sample after the first. If x is a matrix, the function treats each column as a separate sequence. y = downsample( x , n , phase ) specifies the number of samples by which to offset the downsampled sequence.

x = fminsearch( fun , x0 , options ) minimizes with the optimization options specified in the structure options . Use optimset to set these options. x = fminsearch( problem ) finds the minimum for problem , where problem is a structure.

The simplify command is used to apply simplification rules to an expression.

y = decimate( x , r ) reduces the sample rate of input signal x by a factor of r . The decimated signal y is shortened by a factor of r so that length(y) = ceil(length(x)/r) .

Definition of downsampling:

In data engineering, "downsampling" refers to the process of reducing the amount of data for analysis, storage, or processing. This is done by systematically selecting a subset of the data at a lower rate than the original.

To expand or collapse all of the code in a file, place your cursor anywhere within the file, go to the View tab, and select the Expand All or Collapse All buttons.

You can use the general simplification function, simplify , to simplify fractions. However, Symbolic Math Toolbox offers a more efficient function specifically for this task: simplifyFraction .

MATLAB^® supports an important exception, called reduction, to the rule that loop iterations must be independent. A reduction variable accumulates a value that depends on all the iterations together, but is independent of the iteration order. MATLAB allows reduction variables in parfor -loops.

How to solve optimization in MATLAB? ›

sol = solve( prob ) solves the optimization problem or equation problem prob . sol = solve( prob , x0 ) solves prob starting from the point or set of values x0 . sol = solve( prob , x0 , ms ) solves prob using the ms multiple-start solver.

The solve function can solve inequalities and return solutions that satisfy the inequalities. Solve the following inequalities. Set 'ReturnConditions' to true to return any parameters in the solution and conditions on the solution. The parameters u and v do not exist in MATLAB® workspace and must be accessed using S.

Description. M = min( A ) returns the minimum elements of an array. If A is a vector, then min(A) returns the minimum of A . If A is a matrix, then min(A) is a row vector containing the minimum value of each column of A .

Use if, elseif, and else for Conditional Assignment

Loop through the matrix and assign each element a new value.

Solve an Equation

If eqn is an equation, solve(eqn, x) solves eqn for the symbolic variable x . Use the == operator to specify the familiar quadratic equation and solve it using solve . solx is a symbolic vector containing the two solutions of the quadratic equation.
