How do you check if two vectors are the same in Matlab?
Description. tf = isequal( A,B ) returns logical 1 ( true ) if A and B are equivalent; otherwise, it returns logical 0 ( false ). See the Input Arguments section for a definition of equivalence for each data type.
How do two vectors have the same length?
Any two or more vectors will be equal if they are collinear, codirected, and have the same magnitude. If two vectors are equal, their column vectors will also be equal. In other words, two or more vectors are equal if their coordinates are equal. For example, consider the vectors A = (ax1, ay1) and B = (bx1, by1).
What is not equal to in Matlab?

|---|---|---|
| ~= | Not equal to | ne |
| > | Greater than | gt |
| >= | Greater than or equal to | ge |
| < | Less than | lt |
How do you check if two matrices are the same in Matlab?
A == B will return a matrix the same size as A (and B) telling you which elements of A are equal to the corresponding element of B. isequal(A, B) will return a single true/false telling you if all the elements of A are the same as the ones in B.
How do you compare two things in MATLAB?
Description. A == B returns a logical array with elements set to logical 1 ( true ) where arrays A and B are equal; otherwise, the element is logical 0 ( false ). The test compares both real and imaginary parts of numeric arrays. eq returns logical 0 ( false ) where A or B have NaN or undefined categorical elements.
Can the resultant of two unequal forces be zero?
Yes if both forces applied are equal and are in opposite direction. If two unequal forces are exerted on a box the net force could never be zero. It is graphically impossible to take twodirected line segments (vectors) of unequal length and place them tail to tip and end up with a resultant of zero.
What is the meaning of unit vector?
Unit vectors are vectors whose magnitude is exactly 1 unit. They are very useful for different reasons. Specifically, the unit vectors [0,1] and [1,0] can form together any other vector.

What == means in Matlab?
It’s used to compare two variables (numbers, arrays, etc.) and say whether they match or not. This is different than a single = sign, which is an assignment. In a==b you’ll get a single true or false value, or an array of them if a and b are arrays.
