Practice. The find () function in MATLAB is used to find the indices and values of non-zero elements or the elements which satisfy a given condition. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. It returns a vector that contains the linear indices.MATLAB - Division (Left, Right) of Matrics. You can divide two matrices using left (\) or right (/) division operators. Both the operand matrices must have the same number of rows and columns. using a while loop, divide the number 256 by 7 until the value remaining is less than one assign the final value to output variable WhatsLeft and count the number of divisions required and assign the result to variable DivisionCountIf you want the -4 version so that abs () of the "integer part" of -23/5 and 23/5 are the same, then use fix () If you want the -5 version so that the remainder is always non-negative, then use floor () You can use either fix () or floor () if you only have positive values, with floor () being preferred (more efficient, mathematically clearer)15 Des 2010 ... ... division, which is indeed why Matlab makes the matrices full. I was looking for a simple way to only divide the non-zero entries. For my ...opt — Rounding option. 'fix' rounds to the nearest integers toward zero, which is equivalent to removing any digits after the decimal point. 'floor' rounds to the nearest integers toward negative infinity. 'ceil' rounds to the nearest integer toward positive infinity. 'round' rounds to the ...The square root function in MATLAB is sqrt(a), where a is a numerical scalar, vector or array. The square root function returns the positive square root b of each element of the argument a, such that b x b = a.If you want the -4 version so that abs () of the "integer part" of -23/5 and 23/5 are the same, then use fix () If you want the -5 version so that the remainder is always non-negative, then use floor () You can use either fix () or floor () if you only have positive values, with floor () being preferred (more efficient, mathematically clearer)MATLAB Graphics 2-D and 3-D Plots Data Distribution Plots.
