Matlab reference values of a matrix less than

Define less than or equal to condition

Syntax

Description

le( A , B ) is equivalent to A

Examples

Set and Use Assumption Using Less Than or Equal To

Set the assumption that x is less than or equal to 3 by using assume .

syms x cond = x 

Solve an equation for x . The solver only returns solutions that are valid under the assumption on x .


eqn = (x-1)*(x-2)*(x-3)*(x-4) == 0; solve(eqn,x)


ans = 1 2 3


Find Values that Satisfy Condition


Set the condition abs(sin(x)) 

syms x cond = abs(sin(x)) 

Find multiples of π/24 that satisfy the condition by using a for loop from 0 to π.


for i = 0:sym(pi/12):sym(pi) if subs(cond, x, i) disp(i) end end


0 pi/12 pi/6 (5*pi)/6 (11*pi)/12 pi
