T = 2×2 logical array 1 0 0 1 Return only the elements that containsin(x)and replace all other elements with0by multiplyingMbyTelementwise. M.*T ans = [ sin(x)*sin(y), 0] [ 0, 2*sin(x)^2] To check if any of matrix elements contain a particular subexpression, useany. ...
isValid =3x1 logical array1 1 1 Check the motion between each sequential path states. TheisMotionValidfunction interpolates along the path between states. If a path segment is invalid, plot the last valid point along the path. startStates = [path(1,:);path(2,:)]; endStates = [path(...
TF =logical1 Now create a cell array that contains the arrayAand other numbers. Useclassto identify the type of the cell array. Check if it is a numeric type. B = {A -4; 2 1} B=2×2 cell array{2x2 single} {[-4]} {[ 2]} {[ 1]} ...
% The return value A is an array containing the image data. If the file % contains a grayscale image, A is an M-by-N array. If the file contains % a truecolor image, A is an M-by-N-by-3 array. For TIFF files containing % color images that use the CMYK color space, A is ...
6、Cell Array(单元格数组) 1)Another method of storing heterogeneous data(存储异构数据的另一种方法) 2)Similar to matrix but each entry contains different type of data(类似于矩阵,但每个条目包含不同类型的数据) 3)Declared using‘{ }’(使用‘{}’声明) 示例代码一:(此处感谢 @笙歌醉夕阳 纠错)...
Test if3*u.mis a symbolic unit, whereu = symunit. TheisUnitfunction returns logical0(false) because3*u.mcontains the symbolic number3. u = symunit; isUnit(3*u.m) ans = logical 0 Check ifu.m,u.mW, andx*u.Hzare units, whereu = symunit. TheisUnitfunction returns the array[1...
Try using rand to create an array that contains 5 rows and 1 column. Assign the result to a variable named x. >>x = rand(5,1) x = 0.7577 0.7431 0.3922 0.6555 0.1712 Now try using the zeros function to create a matrix of all zeros that has 6 rows and 3 columns (6-by-3). Ass...
