M = mean(A) returnsthe median of the elementsof A follow me the very first array dimension whose sizedoes no equal 1.

You are watching: Mean of a matrix matlab


If A is a vector, climate mean(A) returnsthe median of the elements.

If A is a matrix, climate mean(A) returnsa row vector include the median of each column.

If A is a multidimensional array,then mean(A) operates follow me the very first array dimensionwhose size does not equal 1, treating the facets as vectors. Thisdimension i do not care 1 if the size of all otherdimensions remain the same.


M = mean(A,"all") computes the average over all facets of A. This syntax is valid for MATLAB® version R2018b and later.


M = mean(A,dim) returnsthe mean along measurement dim. Because that example, if A isa matrix, then mean(A,2) is a pillar vector containingthe typical of every row.


M = mean(A,vecdim) computes the mean based upon the dimensions specified in the vector vecdim. Because that example, if A is a matrix, climate mean(A,<1 2>) is the mean of all elements in A, due to the fact that every facet of a procession is included in the array slice characterized by size 1 and also 2.


M = mean(___,outtype) returnsthe median with a stated data type, using any kind of of the entry argumentsin the previous syntaxes. Outtype have the right to be "default", "double",or "native".


M = mean(___,nanflag) specifieswhether to incorporate or omit NaN worths from thecalculation for any type of of the previous syntaxes. Mean(A,"includenan") includesall NaN worths in the calculation if mean(A,"omitnan") ignoresthem.


Create a 4-by-2-by-3 selection of integers between 1 and 10 and also compute the mean values along the 2nd dimension.


M = M(:,:,1) = 8.0000 5.5000 2.5000 8.0000M(:,:,2) = 10.0000 7.5000 5.5000 6.0000M(:,:,3) = 6.0000 5.5000 8.5000 10.0000
Starting in R2018b, to compute the mean over all dimensions of one array, you deserve to either specify each measurement in the vector measurement argument, or use the "all" option.


Data Types: single | twin | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char | datetime | duration


Dimension to run along, specified as a confident integer scalar. If no value is specified, then the default is the an initial array measurement whose dimension does no equal 1.

Dimension dim shows the dimension whoselength reduces come 1. The size(M,dim) is 1,while the sizes of all various other dimensions remain the same.

Consider a two-dimensional input array, A.

mean returns A once dim isgreater 보다 ndims(A) or as soon as size(A,dim) is 1.

Data Types: double | single | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64


Vector of dimensions, stated as a vector of positive integers. Each facet represents a measurement of the intake array. The lengths that the output in the stated operating dimensions room 1, when the others stay the same.

Consider a 2-by-3-by-3 input array, A. Then mean(A,<1 2>) returns a 1-by-1-by-3 array whose aspects are the method over each page of A.

Output data type, stated as "default", "double",or "native". These options additionally specify the datatype in which the procedure is performed.


outtypeOutput data type
"default"double, uneven the input data kind is single, duration,or datetime, in which case, the output is "native"
"double"double, unless the data kind is expression or datetime,in which case, "double" is not supported
"native"same data kind as the input, uneven

Input data type is logical, inwhich case, the output is double
